   Customers may experience DNS resolution failures for their Serverless Functions in the nl-ams and pl-waw regions, due to an error that happened during the scheduled maintenance: https://status.scaleway.com/incidents/qhh06fhhn47r. Errors for clients might look like: "lookup [...] on 10.32.15.25:53: read udp 100.96.xx.xx:xx->10.32.15.25:53: i/o timeout". We have identified the root cause. Sorry about any inconvenience.

2. investigating Apr 28, 2026, 12:11 PM UTC

   We are continuing to investigate this issue.

3. investigating Apr 28, 2026, 12:16 PM UTC

   After investigation, this also affects functions created on new namespaces on fr-par.

4. resolved Apr 28, 2026, 01:50 PM UTC

   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.
