Risolto
Out-of-band access in ZRH has been stable since 08:49 UTC. Duration: 1 h 17 min. Any reinstall or power action queued during the window has been retried and completed.
-
In osservazione
Consoles are reachable again. We are restoring the state sync between the two firewall members.
-
Causa individuata
The firewall pair in front of the ZRH management network lost its state synchronisation and both members went passive. We have forced one member active.
-
In analisi
No IPMI or KVM console in ZRH is reachable since 07:32 UTC. Production traffic is unaffected. Reinstalls and power actions from the customer area will fail for machines in ZRH until this is fixed.

Cosa è successo e cosa è cambiato
Causa
A firmware update on the management-network firewall pair in ZRH reset the state-synchronisation key on one member. When the heartbeat failed, both members concluded the other was active and went passive.
Impatto
IPMI, KVM, reinstalls and remote power actions were unavailable in ZRH for 1 h 17 min. Production connectivity, workloads and data were unaffected.
Cosa abbiamo cambiato
- Firewall firmware updates are now applied one member at a time with an explicit failover test between the two.
- The split-brain guard was changed so that a member with a healthy upstream link stays active rather than going passive.
