LiveHalden Cloud outage · Frankfurt regionDown for 30:45:00

Halden Cloud’s Frankfurt region is down.

Compute, storage and managed Kubernetes in the European provider’s largest region have been unavailable since 06:12 CET. Hospitals, three city councils and hundreds of firms are affected. We are following the recovery and asking what it means for sovereign-cloud promises.

What we know

  1. A cooling failure at one of three Frankfurt data halls triggered an automatic shutdown at 06:12 CET. A failover to the other two halls did not complete.
  2. Halden Cloud says no customer data has been lost. Storage is replicated; the problem is access, not durability.
  3. Customers running in two regions recovered within minutes. Single-region customers are still waiting.
  4. The provider has filed an early warning with its national authority, as NIS2 requires within 24 hours of a significant incident.

  6. Halden Cloud chief technology officer speaks

    On a call with customers and press, the company’s CTO explained why the failover stalled: a configuration check blocked the move because the two remaining halls would have run above their safe power limit.

    The safety check did what it was designed to do. The design was wrong, and that is on us.

  7. Key moment

    Root cause identified: cooling failure, then a stalled failover

    Halden Cloud confirmed that a chiller fault in hall B forced an automatic shutdown. Automated failover to halls A and C began but was halted by a capacity safeguard.

  8. Three city councils and two hospital groups affected

    Online permit services in three councils are offline. Two hospital groups say clinical systems are running on local fallbacks; appointment booking and staff email are down.

  9. Why this matters beyond Frankfurt

    Halden Cloud is one of the providers most often named in public tenders that require EU ownership. Today tests a claim at the heart of the sovereignty debate: that local control can come with hyperscaler-grade resilience.

  10. Key moment

    Provider files NIS2 early warning

    Halden Cloud says it has notified its national authority, as the directive requires within 24 hours of a significant incident. A fuller notification is due within 72 hours.
