Recent incidents

Every issue that affected at least 1% of customers, with what we did about it.

1. Mar 18, 2026 Duration: 8 minutes minor

   Brief WebSocket drop in the EU region

   Impact: Live-cursor presence and real-time edits lagged or briefly disconnected for users routed through Frankfurt. Saved boards were not affected.

   Resolution: Failed over to the secondary collab cluster and shipped a fix to the upstream proxy that triggered the disconnect storm.

2. Feb 24, 2026 Duration: 31 minutes minor

   Image uploads slow

   Impact: Uploads larger than 5 MB took 3–10s longer than usual; smaller uploads were unaffected.

   Resolution: Storage provider acknowledged a regional throttling issue and lifted the cap. Added an additional retry path on our side as a precaution.

3. Jan 09, 2026 Duration: 1 hour 12 minutes low

   API rate-limit headers missing

   Impact: Customers integrating against the API saw 429 responses without the usual `Retry-After` header. No data was lost; well-behaved clients retried successfully.

   Resolution: Patched the rate-limit middleware to always emit the header and added a regression test.
