Amplitude vs PostHog
Front door check counts, what each vendor’s status page recorded and SLA terms for these vendors.
30-day window ending
Front door checks
Every 15 minutes we send a request to a documented endpoint for each vendor from a single CheckUpstream location and count the answers. A reachable front door does not confirm that a customer action worked.

Checks 15 minutes apart cannot see disruptions shorter than that. Each vendor is checked at its own endpoints, so the counts cover different things.

What each vendor’s status page says
Recorded starts in the same 30-day window, excluding maintenance. Vendors report incidents differently; fewer posts don’t prove better reliability.
| Last 30 days | Amplitude | PostHog |
|---|---|---|
| Incidents recorded | 7 | 9 |
| Recorded incident durationMedian | 1h 37m 7 valid durations | 36m 9 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.

An SLA applies to specific products and plans. Credit eligibility also depends on exclusions, evidence and filing deadlines.
