Control Plane Services (SysEleven - CBK) INCIDENT: Partial outage of Control Planes in Regions FES, DBL, CBK

Affected Components: Control Planes in Regions FES, DBL, CBK

Incident Start: 2024-12-09 18:30 UTC+01:00 (CET)

Description:

Some cluster control planes are not reachable.

Update (22:20 CET):

We have found a way to mitigate the issues temporarily and start applying the fix.

Update (22:50 CET):

We applied the fix everywhere. We don't see any broken clusters anymore.

Update 2024-12-10 12:30 UTC+01:00 (CET):

We identified the root cause: An unintended side-effect of an upgrade to a kube-proxy setting changed the proxy mode. This created iptables rules which were not cleaned up and through which traffic was dropped.

We are taking measures to prevent this in the future.
