I made this site because I wanted to filter GitHub's incident history for the services and severity levels that affect the products I build.
Everybody's reliability narrative is a function of the services they depend on and the 9's they expect. Use the filters above to dial in on yours.
Your filter set might be different from somebody else's. Now you can declare yours and avoid talking past each other!
GitHub has had 1064 incidents since March 2016, implying a monthly incident rate of 25 (↓ 10% vs prev 3mo).
During that time, their longest streak without an incident was 8 days, ending Dec 31, 2025, and the worst month was February 2026 with 37 incidents.
