Heroku incidents in September 2026
Heroku reported all systems operational on every check we recorded in September 2026.
How we measure this
About once an hour we read Heroku's official status feed and record exactly what it says — we don't infer status from our own connection to them. When the feed can't be read, we record nothing rather than guess, so a gap in the chart above means “not monitored”, never “down”.
Uptime is the share of the 101 recorded checks where Heroku was not reporting an outage — a provider flagging degraded service is still up. Providers often sit at “degraded” for days over one small component, so counting that as downtime would say a service was offline all month when its own page said nothing of the kind. Degradation is reported separately, in the figures above and the timeline below.
This is a sample, not continuous monitoring: an incident that started and finished between two checks won't appear here, and a run can be missed. Treat these figures as what Heroku was reporting at the moments we looked — the official page is the authority. Official Heroku status page →
