Minor incident GINA partially unavailable in CH instance
[Resolved]

After an extended monitoring period, we see that all customer GINA domains are fully functional again.

The root cause of the issue was that an internal operation to refresh all customer GINA domains was aborted during execution. After the refresh was restarted, the affected GINA domains were working again.

We are reviewing the cause of the aborted execution and will implement measures to avoid the impact of such a situation.
