Affected Components: MetaKube apiserver external availability, some clusters, DBL/CBK
Incident Start: 10.Feb 2024/11:00 am
Incident End: 10. Feb. 2024/12:35 am
Description:
An expired client certificate caused some load balancer configuration to go stale.
Thus, a small number of clusters lost external availability of their apiservers.
Customer Impact:
- External apiserver availability disrupted for at most 8 clusters at peak for a maximum of 95min
Customer Actions:
Examples:
- No customer actions needed
Update 12:35
The certificate was renewed and a failover of the load balancer triggered.
This restored availability of all clusters again.
