View Supabase recordWhat the incident records say
Recorded starts in the same 30-day window, excluding maintenance. Vendors report incidents differently; fewer posts don’t prove better reliability.
| Last 30 days | Clerk | Supabase |
|---|---|---|
| Incidents recorded | 5 | 14 |
| Recorded incident durationMedian | 1h 9m 5 valid durations | 2h 42m 14 valid durations |
Duration uses at least 5 incidents with vendor-supplied starts and recorded closure times. First-observed starts are excluded. A record may close when a post disappears or our tracking period expires; this does not confirm recovery. A missing closure time does not mean an outage is ongoing.
