[Serverless Containers] - [fr-par] - issues connecting to resources inside Private Network

Update timeline

1. investigating Aug 17, 2026, 04:41 PM UTC

   On a small subset of our fr-par infrastructure, between 2026-08-17 09:20 UTC and 2026-08-17 16:15 UTC, some containers attached to a Private Network were not able to reach resources inside that PN. This issue is likely due to a faulty deployment, that we have reverted at 2026-08-17 16:15 UTC. Containers should now be able to reach resources in their Private Network as before. If your container has faced issues like "timeouts" or "connection error" while trying to reach a resource through their private endpoint during the time range above, the issues are likely linked. If you still continue to face these errors, feel free to open a support ticket. We sincerely apologize for any inconvenience.

2. monitoring Aug 17, 2026, 04:48 PM UTC

   We have finished rolling back the faulty deployment. Situation should be good now for all users.

3. resolved Aug 18, 2026, 01:26 PM UTC

   After investigation, we have found the root cause. The issue happened because of blackholed traffic, but only on some Private Networks with a specific configuration: - PNs with ACLs - PNs inside VPCs with "enable_routing" set to false Anyway, we have rolled back the component causing the issues, so this error shouldn't happen anymore. Sorry again for any inconvenience.
