## Updates from Scaleway
### 2026-04-28 12:06 UTC: investigating
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.

### 2026-04-28 12:11 UTC: investigating
We are continuing to investigate this issue.

### 2026-04-28 12:16 UTC: investigating
After investigation, this also affects functions created on new namespaces on fr-par.

### 2026-04-28 13:50 UTC: resolved
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.
