We decided to upgrade to next compute tier - this resolves the issue.

Resource: Azure Database for PostgreSQL flexible server
Compute: Burstable, B1ms, 1 vCores, 2 GiB RAM, 32 GiB storage
Hi,
Last maintenance window was on 1. June 2025. After that planed downtime a few unplanned unavailability events appeared in resource health events.
I also notice a unexpected >80% CPU load. This seems to happen because all CPU Credits were used until 14. June 2025. I never had problems with my CPU usage the database is mostly in IDLE mode. But after the maintenance the CPU spiked more often, drained the CPU credits and server was unavailable a few times. I manually restarted the server but it seems to persist.

2025-06-15T10:01:05.96+00:00 Average "CPU percentage from platform" increased a bit after the maintenance update. Current compute tier makes only sense if average CPU is below 20% - maybe Microsoft forces me to upgrade my compute tier with a maintenance update :D
