GitHub Struggles With Service Reliability, Falling Below 90% Uptime in 2025
Key Takeaways
- ▸GitHub experienced multiple significant outages in February 2025, affecting pull requests, Actions, notifications, and Copilot functionality
- ▸The platform's uptime fell below 90 percent at one point in 2025, well below its stated 99.9 percent SLA target for Enterprise Cloud customers
- ▸Copilot policy propagation issues prevented users from accessing newly enabled models for over 15 hours
Summary
GitHub, Microsoft's code collaboration platform, has experienced significant stability issues throughout early 2025, with multiple outages affecting core services including Actions, pull requests, notifications, and Copilot. On February 9 alone, the platform suffered notification delays of approximately 50 minutes and a Copilot policy propagation issue that lasted over 15 hours, preventing users from accessing newly enabled models. According to reconstructed status data from public feeds, GitHub's uptime dropped below 90 percent at one point in 2025, falling well short of the 99.9 percent (three nines) availability specified in its Enterprise Cloud Service Level Agreement.
The recurring outages underscore growing concerns about cloud service reliability across the industry, where many platforms struggle to maintain consistent uptime despite customers' critical dependence on them. While GitHub's SLA guarantees 99.9 percent uptime for Enterprise Cloud customers, the company does not extend this guarantee to all users, leaving many dependent on the platform vulnerable to service disruptions.
- GitHub's status page redesign has made it harder for users to track historical availability and uptime trends
- The platform joins other cloud services in struggling to maintain reliable service levels that customers depend on
