We experienced a small fiber cut between two AZ of the Paris region between 10:06 and 10:07 UTC. While the impact should have been minimal, it seems to have not been the case. Some services might have encountered timeouts or errors when reaching them up until a few minutes after the cut happened.
We are investigating the issue.
EDIT 11:50 UTC: We believe to have found the underlying issue. Some network routes were still stale and tried to use the dead links for multiple seconds. This lead to the timeouts or various services degradation. We will update our configurations to avoid this issue in the future.
