Elevated errors creating and connecting to browsers

Update timeline

1. identified Nov 04, 2026, 02:12 AM UTC

   Since 5:44pm PT (01:44 UTC), some requests to create a browser are failing with 529 capacity errors, and some newly created browsers are rejecting CDP connections. We've identified the cause and are rolling out a fix. If a browser created during this window won't connect, delete it and create a new one. We'll post another update once it's resolved.

2. monitoring Nov 04, 2026, 02:31 AM UTC

   As of 6:27pm PT, a fix has been deployed and browser creation and connections have recovered. Browsers created between 5:44pm and 6:27pm PT that won't connect should be deleted and recreated. We're monitoring.

3. resolved Nov 04, 2026, 02:41 AM UTC

   This incident is resolved. Browser creation and connections are healthy again as of 6:27pm PT. If a browser created between 5:44pm and 6:27pm PT still won't connect, delete it and create a new one.
