The root cause has been fixed: all functions now have a working DNS again. The incident is now closed.
Impacted functions were:
- on fr-par, only functions not attached to a private network, that belong to a namespace created after 2026-04-28 8:00 AM UTC, until 1:05 PM UTC.
- on nl-ams, all functions not attached to a private network, between 8:41 AM UTC and 1:46 PM UTC
- on pl-waw, all functions not attached to a private network, between 9:30 AM UTC and 1:05 PM UTC
The incident on nl-ams and pl-waw is related to the scheduled maintenance https://status.scaleway.com/incidents/zrhfpqjvjyrl. A mismatch between DNS service IPs caused the issue.
We deeply apologize for the inconvenience.
