# Bunny.net: Major incident: Isolated 502s for Magic Containers

**Summary:** Major isolated 502s affected North American CDN endpoints using Magic Containers and Databases, starting 2026-04-30 10:12 UTC and resolved 2026-05-26 08:23 UTC (25 days 22 h). Database routing adjustments restored service; Bunny.net later fixed delayed endpoint synchronization between Magic Containers and CDN routing, linked to slow sticky session invalidation that left stale endpoint data in use. _(machine-written, sol)_

```diff
+ Our Engineering team are still investigating the root cause for isolated 502s in the NA region.
```

**11. Added: Update** (monitoring) · 2026-05-06 14:29 UTC

```diff
+ We are monitoring improvements related to the resilience of routing configuration failover on edge servers during temporary control plane connectivity interruptions.
```

**12. Added: Update** (resolved) · 2026-05-26 08:23 UTC

```diff
+ We identified and resolved an issue that could cause endpoint updates to experience delayed propagation after CDN services had been running for an extended period of time. The issue was related to endpoint synchronization between Magic Containers and the CDN routing component, where slower processing connected to sticky session invalidation could result in stale endpoint data remaining in use longer than expected.
