Incident with Packages
Final update
On November 3, 2025, between 14:10 UTC and 19:20 UTC, GitHub Packages experienced degraded performance, resulting in failures for 0.5% of Nuget package download requests. The incident resulted from an unexpected change in usage patterns affecting rate limiting infrastructure in the Packages service. We mitigated the issue by scaling up services and refining our rate limiting implementation to ensure more consistent and reliable service for all users. To prevent similar problems, we are enhancing our resilience to shifts in usage patterns, improving capacity planning, and implementing better monitoring to accelerate detection and mitigation in the future.
