We saw elevated error rates on scheduling checks in multiple regions from 11:30 to 12:00 PM CET. This could have resulted in failed checks. The underlying cause is in our upstream cloud provider. We do not have a root cause yet.
The situation seems to have resolved at roughly 12:00 PM CET. We are monitoring the situation.
Update 01:00 PM: Upstream provider is stable in all regions for the last 30 minutes. We consider this incident closed but will monitor stability as normal.
