Physical Datacenter Migration in Sweden: What It Is and What It Is Not

Datacenter migration means moving your physical infrastructure from one cage, suite, building or operator to another. It is not cloud migration. It is not a software project. It is engineers inside a facility decommissioning cables, labeling hardware, staging equipment in a loading bay, racking servers in a new hall, reconnecting power and network, and running validation before you cut traffic over. Sweden hosts over 57 carrier-grade facilities spanning Stockholm, Malmö and Gothenburg, with the heaviest concentration in Stockholm's Kista, Akalla and Älvsjö districts. Many Swedish enterprises find themselves mid-lease at one facility while a more capable building sits a few kilometres away. That gap between where your infrastructure lives and where it should live is where Reboot Monkey operates.

Why Swedish Enterprises Are Migrating Right Now

Several converging pressures are driving physical datacenter migrations across Sweden at a pace not seen in earlier years.

Power density constraints. Older Stockholm facilities such as Equinix SK1 in Kista support 10-12 kW per rack. GPU and AI workloads regularly demand 20-25 kW per rack. Equinix SK4 in Akalla and newer Digital Realty STO1 capacity in Älvsjö can accommodate those densities. Enterprises running out of power headroom migrate to the newer buildings rather than throttle their workloads.
Facility end-of-life and lease expiry. Several facilities in the Kista technology district are scheduled for infrastructure refresh. Tenants approaching lease renewal are evaluating whether to renew or consolidate into a higher-tier site.
Compliance-driven relocation. Sweden's NIS2 transposition via the Cybersecurity Act imposes 72-hour incident notification obligations to PTS (the Swedish Post and Telecom Authority) for critical infrastructure tenants. Some operators in energy, finance and telecommunications are consolidating infrastructure into facilities with better redundancy and audit capabilities to meet these obligations.
Geographic redundancy. Enterprises building active-active DR architectures are adding a second site in Malmö or Gothenburg as a complement to their Stockholm primary. The Stockholm-Gothenburg corridor spans roughly 470 km. Stockholm to Malmö is approximately 600 km, and Malmö connects to Copenhagen via the Øresund Bridge, making it a useful cross-border node.
Operator cost optimisation. Migrations from Equinix tier-1 pricing to operators such as GleSYS, Bahnhof Annedal or Conapto are common for cost-sensitive workloads where the connectivity premium of an Equinix campus is not justified.

Swedish Datacenter Facilities: The Operator Landscape

Reboot Monkey works inside all major Swedish facilities. Understanding the operator landscape is essential before planning any migration.

Equinix SK1 (Kista): the oldest and largest Equinix campus in Stockholm, hosting Netnod Stockholm GREEN and BLUE internet exchange switches. 171 connected networks. Standard rack power 10-12 kW. Frequent origin point for power density migrations to SK4.
Equinix SK2 (Kista): expansion facility adjacent to SK1. Standard power 12 kW, up to 15 kW available. Routine SK1-to-SK2 migrations managed within the same Kista campus with short cabling runs.
Equinix SK3 (Älvsjö): geographically separate facility 8 km south of Kista. Modern design, 15 kW standard, 400G optics capable, lower PUE than SK1. Cross-campus migrations from SK1 to SK3 require full circuit reprovisioning.
Equinix SK4 (Akalla): newest Stockholm facility, highest power density available (20-25 kW per rack), best PUE in Sweden at approximately 1.18. Primary destination for AI and GPU-intensive workloads moving from older buildings.
Digital Realty STO1 (Älvsjö): formerly Interxion, now part of Digital Realty. Carrier-neutral, 125 connected networks, water-cooled using proximity to the Älvsjö river. Critical Nordic interconnection hub. STO1 and Equinix SK3 are 2 km apart, making cross-operator migrations between them logistically manageable.
Bahnhof Annedal (Bromma): Swedish-owned, carrier-neutral, lower cost bracket than Equinix and Digital Realty. 42 connected networks. Common destination for enterprises optimising OpEx while retaining Stockholm presence.
GleSYS (Stockholm and Falkenberg): Swedish managed hosting provider with its own facilities. Falkenberg site attracts regional workloads from smaller Halland-area operators.
Conapto: newer carrier-neutral facilities in Stockholm growth zones, attracting enterprises that want modern infrastructure without the Equinix price point.
Malmö and Gothenburg: Stena Fastigheter, GlobalConnect and Göteborg Energi serve the southern and west coast markets respectively. Fewer operators and lower connectivity density than Stockholm, but useful for regional redundancy and Danish cross-border reach.

GDPR, IMY and NIS2: The Compliance Layer Every Swedish Migration Needs

Swedish datacenter operators and their tenants operate under a compliance stack that is stricter in practice than in most other EU markets. Reboot Monkey's project managers are familiar with the obligations that affect your migration window.

GDPR and IMY enforcement. The Swedish Authority for Privacy Protection (Integritetsskyddsmyndigheten, IMY) is one of Europe's most active GDPR enforcers. Any migration that involves moving systems that process personal data requires a data processing impact assessment if there is a change in processor or a new data transfer chain. Migrations between Swedish facilities are the lower-risk scenario because both sites remain under IMY jurisdiction. Migrations that move data to non-EU destinations require Standard Contractual Clauses and adequacy assessments.
NIS2 . Sweden transposed the NIS2 Directive into the Cybersecurity Act . Organisations in essential sectors including energy, financial services, telecommunications, healthcare and water must notify PTS within 72 hours of a significant incident that affects service availability. A poorly planned migration that causes an availability event longer than 30 minutes may trigger this obligation. Reboot Monkey builds maintenance windows, rollback checkpoints and parallel-running periods into migration plans to keep availability disruptions below threshold where possible.
ISO 27001 and audit trail requirements. Most tier-1 Swedish facilities hold ISO 27001 certification. Migrating into or out of a certified facility often requires documented evidence of secure handling during the transition period. Reboot Monkey produces pre-migration asset inventories, cutover checklists and post-migration validation reports that can be retained for compliance audits.
PCI DSS for fintech and e-commerce. Stockholm is a significant fintech and gaming hub. Any infrastructure migration touching payment card data must maintain PCI DSS continuity. This includes maintaining encryption in transit, access control documentation and change management records throughout the migration window.

How Reboot Monkey Executes a Physical Datacenter Migration in Sweden

Physical migration is a hands-on, staged process. There is no remote workaround for pulling a cable. Reboot Monkey's approach is structured to minimise risk at each transition point.

Pre-migration audit. On-site engineers inventory every rack, cable, cross-connect and power circuit at the source facility. We document vendor hardware (Dell, HP/HPE, Cisco, Juniper, Arista, Supermicro, Lenovo), serial numbers, cable types, power draw per rack and network topology. Nothing moves without a baseline.
Cutover plan development. Based on the audit, we produce a sequenced migration plan. Critical workloads move last, with the longest parallel-running window. Batch groupings are designed around power budget at the destination, rack density and BGP / DNS cutover timing. For Netnod peering customers, we coordinate peering rebalancing across GREEN and BLUE switches prior to cutover.
Physical relocation. Engineers at the source facility decommission hardware in agreed sequence, label everything, and stage equipment. Simultaneously, engineers at the destination facility prepare racks, verify power circuits (all Swedish facilities run on 230V/50Hz, three-phase 400V distribution), and test cooling. For cross-city migrations on the Stockholm-Gothenburg (~470 km) or Stockholm-Malmö (~600 km) corridors, we coordinate secure transport logistics and ensure destination readiness before hardware leaves the source.
Network cutover and validation. DNS changes, BGP route updates and cross-connect provisioning happen in the agreed maintenance window. Reboot Monkey engineers remain on-site at both source and destination during cutover. We run health checks, latency tests and application-layer validation before declaring success.
Rollback readiness. Source infrastructure remains in a runnable state until post-migration validation passes. If a critical failure occurs during cutover, we reverse the DNS and routing changes and return traffic to the source without waiting for approval chains.
Post-migration documentation. After validation, we produce an as-built asset register for the new facility, a migration report for compliance records and recommendations for decommissioning the vacated space.

Power Infrastructure Considerations for Sweden Migrations

Sweden runs on 230V/50Hz as per the IEC 60038 European standard. Three-phase 400V distribution is standard in all listed datacenters, with line-to-neutral single-phase at 230V. This is consistent across Equinix, Digital Realty, Bahnhof, GleSYS and Conapto. Where migrations create risk is in power density transitions. Moving equipment designed around a 10 kW per rack budget into a facility with 20-25 kW capability does not automatically increase your delivered power. Reboot Monkey engineers verify PDU configurations, circuit breaker ratings and UPS topology at the destination before staging any hardware. For high-density GPU workloads moving to Equinix SK4 or newer Digital Realty STO1 halls, we confirm that the destination cooling design (free-cooling first, chiller backup) is correctly provisioned for the thermal load. Sweden's power grid is among Europe's most stable, with voltage variation typically within 1% and total harmonic distortion below 0.5%. The grid is approximately 97% renewable, drawing on hydroelectric, nuclear and wind generation. Power cost in Swedish facilities ranges from 0.04 to 0.08 EUR/kWh, which is competitive compared to most Western European markets. This energy cost advantage is itself a migration driver for power-intensive workloads relocating from higher-cost regions.

Internet Exchange Peering Continuity During Migration

Stockholm hosts three internet exchanges relevant to migration planning: Netnod Stockholm GREEN (187 member networks), Netnod Stockholm BLUE (177 member networks) and STHIX (85 member networks), with SONIX serving both Stockholm and Gothenburg as a community-driven exchange. For enterprises with active peering sessions, migration between facilities requires advance coordination with exchange operators. Moving from Equinix SK1 to SK3 or STO1, for example, changes the physical port where your peering sessions terminate. Reboot Monkey project managers include a peering audit in the pre-migration scope. We work with your network team to map existing BGP sessions, coordinate port provisioning at the destination exchange point, and validate session establishment before cutting over traffic.

Migration Corridors: Stockholm, Gothenburg and Malmö

Most Swedish migration volume originates or terminates in Stockholm, which holds approximately 35-40% of the country's datacenter capacity across its 20 facilities. For inter-city migrations, the corridor characteristics matter.

Stockholm to Gothenburg (~470 km): Sweden's busiest inter-city business corridor. Enterprises with a Stockholm primary and a Gothenburg DR site are common in the manufacturing, port logistics and industrial sectors. Circuit provisioning between the two cities relies on Telia Carrier and GlobalConnect fibre routes. Latency between Stockholm and Gothenburg is typically 5-7 ms on direct fibre paths.
Stockholm to Malmö (~600 km): the southern corridor connects Stockholm to Skåne and, via the Øresund Bridge crossing, to Copenhagen and Denmark. Malmö is growing as a second-site option for enterprises wanting Scandinavian presence without duplicating Stockholm. Facilities here include Stena Fastigheter and GlobalConnect Malmö. Transit latency to Copenhagen from Malmö is in the 3-5 ms range.
Intra-Stockholm campus migrations: the most common and lowest-risk migration type. SK1 to SK2 within the Kista campus involves cable runs measured in tens of metres. SK1 or SK2 to SK3 (Älvsjö, 8 km away) or SK4 (Akalla, north Stockholm) require full circuit reprovisioning but remain within the same metropolitan fibre network.

Reboot Monkey's Position in the Swedish Market

Reboot Monkey is a vendor-neutral, operator-independent provider of physical datacenter services. We are not a colocation operator, not a managed service provider, and not an IT consultancy. We put engineers inside facilities to do physical work. That independence matters in migration projects. When Equinix or Digital Realty field services teams manage a migration, their incentive is to keep you within their own facility portfolio. Reboot Monkey has no stake in which facility you land in. Our job is to execute the move accurately and quickly, regardless of which operator you are leaving or joining. Our global network covers 250+ cities across 190 countries, which means that multi-site migrations, Swedish-to-international relocations, or pan-Nordic consolidation projects all run under a single contract and a single point of escalation. For Swedish operations, we maintain a 4-hour on-site engineer dispatch SLA in Stockholm. Our 24/7 NOC coordinates project status, incident response and vendor liaison in real time throughout a migration window. We are experienced across regulated industries: financial services, media and broadcasting, healthcare, telecommunications, and government. These sectors have the strictest compliance documentation requirements during infrastructure transitions, and our migration methodology is designed to produce the audit trail they need.

Common Migration Scenarios and Timelines

Understanding what your migration involves helps set realistic expectations for budget and schedule.

Intra-campus cage or suite relocation (e.g., SK1 to SK2, same Kista campus): 1-2 weeks including audit, cable staging and cutover. Lowest complexity, minimal circuit reprovisioning.
Cross-campus migration within Stockholm (e.g., SK1 to SK3 Älvsjö, or SK3 to SK4 Akalla): 3-6 weeks. Full circuit reprovisioning, potential peering rebalance, cooling and power validation at destination.
Operator change in Stockholm (e.g., Equinix to Digital Realty STO1, or either to Bahnhof): 6-10 weeks. Cross-connect removal and re-installation at both facilities, BGP session migration, full redundancy rebuild.
Inter-city migration (Stockholm to Malmö or Gothenburg): 8-12 weeks. Site survey at both ends, long-haul circuit provisioning, latency budgeting, failover architecture design, parallel running period.
Large-scale facility refresh (50+ racks, multiple customers): 3-18 months depending on scope. Phased cutover plan, tenant coordination, operator liaison for facility access scheduling.

Bundling Migration With Adjacent Services

Physical datacenter migration rarely exists in isolation. Reboot Monkey offers all 11 physical datacenter services under a single contract, which means migration projects can draw on adjacent services without adding vendor complexity.

Rack and stack at the destination facility: engineers prepare and install racks, cable management and power circuits before hardware arrives.
Remote hands and smart hands during the migration window: on-site presence for real-time troubleshooting during cutover, without the cost of a full project team sitting idle between tasks.
Server migration for individual workloads being relocated independently of the broader facility move.
Data center decommissioning of the vacated space: asset disposition, cable removal, cage handback coordination with the source facility operator.

Individual server relocation within or between Swedish facilities, including hardware validation and network reconfiguration.

On-demand engineer presence inside Swedish datacenters for hardware tasks, reboots, cabling and troubleshooting.

Skilled technician support for complex configuration work, installations and diagnostic tasks across Swedish facilities.

Physical rack installation, hardware mounting, cable management and power provisioning at any Swedish datacenter.

Structured decommissioning of vacated Swedish datacenter space, including asset inventory, cable removal and cage handback.

Frequently Asked Questions: Datacenter Migration in Sweden

What is the difference between datacenter migration and cloud migration?

Datacenter migration means physically moving your servers, networking gear and storage from one facility to another. Engineers handle the hardware directly: decommissioning cables, staging equipment, transporting it, racking and reconnecting it at the destination, and validating connectivity before you cut traffic over. Cloud migration moves workloads from physical infrastructure into a virtualised cloud environment. Reboot Monkey focuses exclusively on physical migration. If you need to move a cage, suite or full building of infrastructure from Equinix SK1 to SK4, or from Stockholm to Malmö, that is our work.

How long does a datacenter migration typically take in Sweden?

Timeline depends heavily on scope and migration type. Intra-campus moves within the same Stockholm facility cluster, such as SK1 to SK2 in Kista, can complete in 1-2 weeks including audit and cutover. Cross-campus migrations within Stockholm, such as Kista to Älvsjö or Akalla, typically take 3-6 weeks for circuit reprovisioning and validation. Operator changes, for example moving from Equinix to Digital Realty STO1, require 6-10 weeks to rebuild cross-connects and BGP sessions. Inter-city migrations between Stockholm and Gothenburg (~470 km) or Stockholm and Malmö (~600 km) typically take 8-12 weeks. We provide a specific timeline estimate after the pre-migration audit.

Can you migrate a datacenter without downtime?

Planned maintenance windows are usually required, but the goal is to keep any outage to a brief, pre-agreed window rather than an uncontrolled event. Reboot Monkey builds cutover plans around parallel-running periods, where source and destination infrastructure both carry traffic briefly before the source is decommissioned. We design rollback checkpoints so that if validation fails at cutover, we can return traffic to the source without waiting for approvals. For NIS2 essential entity tenants in Sweden, we specifically target maintenance windows that keep any availability disruption below the 30-minute PTS notification threshold.

Does Reboot Monkey work at all Swedish datacenter facilities?

Yes. Reboot Monkey is vendor-neutral and operator-independent. We work inside Equinix SK1, SK2, SK3 and SK4 in Stockholm, Digital Realty STO1 in Älvsjö, Bahnhof Annedal in Bromma, GleSYS in Stockholm and Falkenberg, Conapto, Stokab municipal facilities, GlobalConnect in Malmö and Gothenburg, and all other carrier-grade facilities across Sweden. You do not need to select a facility that is in our network because all facilities are in our network.

What are the GDPR and NIS2 requirements for a datacenter migration in Sweden?

Under GDPR, any migration involving systems that process personal data requires assessment of whether the migration changes the data processing chain or introduces new processors. Migrations between Swedish facilities are the lower-risk scenario because both sites remain under IMY jurisdiction. Under Sweden's Cybersecurity Act , which implements NIS2, organisations in essential sectors must notify PTS within 72 hours of a significant incident affecting service availability. Migrations involving critical infrastructure tenants should include maintenance windows designed to avoid availability events exceeding the 30-minute notification trigger. Reboot Monkey produces the documentation required for both GDPR and NIS2 compliance records during and after migration.

What power standard do Swedish datacenters use?

Sweden uses 230V/50Hz (single-phase, line-to-neutral) per IEC 60038, with three-phase 400V distribution standard in carrier-grade facilities. This applies to Equinix, Digital Realty, Bahnhof, GleSYS, Conapto and all other Swedish operators. When migrating hardware between facilities, Reboot Monkey verifies PDU configurations, circuit breaker ratings and UPS topology at the destination before staging any equipment.

How do you handle internet exchange peering continuity during a migration?

Enterprises with active peering sessions at Netnod Stockholm GREEN or BLUE, STHIX or SONIX need to plan peering continuity as part of the migration scope. Moving between facilities changes the physical port where your BGP sessions terminate. Reboot Monkey includes a peering audit in the pre-migration scope, coordinates port provisioning at the destination exchange point, and validates session establishment before cutting over traffic. For Netnod customers specifically, we coordinate with the exchange operator on port scheduling to minimise disruption to peering sessions.

Can Reboot Monkey handle migrations between Stockholm and Gothenburg or Malmö?

Yes. Reboot Monkey has field engineer coverage in Stockholm, Gothenburg and Malmö. Inter-city migrations on the Stockholm-Gothenburg corridor (~470 km) and the Stockholm-Malmö corridor (~600 km) fall within our standard service scope. These projects require site surveys at both ends, long-haul circuit provisioning, and a longer parallel-running period compared to intra-city moves. We coordinate secure hardware transport and ensure destination facility readiness before equipment leaves the source.
