- postmortem
On July 30, 2026, between approximately 11:00 and 15:57 UTC, some customers could not load sheets and experienced API timeouts. This also affected Control Center, Table View, Timeline and Board views, Reports, Dashboards, Forms, Dynamic View, and Bridge integrations. The cause was a backend service that came under heavy CPU load during the morning traffic ramp-up. Its automated health checks began removing overloaded instances faster than replacements could come online, and the service's minimum capacity setting was too low to absorb the loss. Our engineers resolved the issue by raising the service's capacity limits, which restored healthy capacity and returned performance to normal within minutes. No data was lost. We have permanently raised the capacity floor, and we are tuning the health checks, adding earlier infrastructure-level monitoring, and building a runbook to prevent and speed recovery from similar issues.
