GitHub appears to be struggling with one nine availability

"GitHub has had a rough month so far. On February 9, Actions, pull requests, notifications, and Copilot all experienced issues. The Microsoft tentacle admitted it was having problems with "some GitHub services" at 1554 UTC before it confessed to notification delays of "around 50 minutes". It took until 1929 UTC for the company to confirm that things were back to normal, although the delay was down to "approximately 30 minutes" by 1757 UTC."

"GitHub changed its status page a while ago, making it harder to visualize the availability of its services. Yes, the details are front and center, but getting a sense of how things have gone over the last 90 days, particularly overall uptime, is trickier. The "missing" status page exists in reconstructed form via the public status feed, though this is an unofficial source so requires caution. It reveals that GitHub's stability has been poor: uptime dropped below 90 percent at one point in 2025."

"The code shack isn't alone in experiencing service instability. While five nines (99.999 percent uptime) represents the gold standard, some vendors struggle to maintain even 90 percent - a concern for customers relying on these platforms. GitHub's Service Level Agreement for Enterprise Cloud customers specifies 99.9 percent uptime, although the company does not guarantee this for all users. The travails of GitHub customers highlight the need to plan for downtime as well as uptime."

GitHub experienced multiple outages and service issues in February 2025, affecting Actions, pull requests, notifications, and Copilot. Notification delays reached around 50 minutes, with partial recovery and delays reduced to approximately 30 minutes later the same day. Copilot suffered policy propagation problems from 1629 UTC on February 9 to 0957 UTC on February 10, preventing newly enabled models from appearing for some users. GitHub altered its status page, making 90-day uptime trends harder to visualize; reconstructed public feeds indicate uptime dipped below 90 percent at one point in 2025. Enterprise Cloud SLA specifies 99.9 percent uptime, but not all users are covered. Customers are advised to plan for downtime as well as uptime.
