GitHub experienced four significant service disruptions in October 2025, affecting various services including Codespaces and GitHub Actions. The incidents were caused by network issues and third-party outages.
GitHub faced multiple service disruptions in October 2025, with four major incidents impacting various services. These disruptions were caused by network issues and external dependencies, according to GitHub's report.
Key Incidents and Their Impact
The first incident occurred on October 9, 2025, when a network device was inadvertently brought back into service before repairs were completed. This led to significant packet loss and increased latency for authenticated users accessing GitHub.com. The incident lasted nearly two hours, affecting API users and delaying 24% of Actions service runs.
On October 17, a configuration error in cloud resources led to a 70-minute outage in mobile push notifications across all regions. GitHub is reviewing its procedures to prevent similar occurrences in the future.
October 20 saw a two-hour disruption in the Codespaces service due to a failure in a third-party dependency. This caused a high error rate in creating and resuming codespaces, with the error rate peaking at 71% for new codespaces. GitHub plans to reduce reliance on such dependencies to mitigate future risks.
The most severe incident happened on October 29, lasting nearly seven hours due to a widespread outage at a third-party provider. This led to significant connection issues for Codespaces users and affected GitHub Actions, resulting in workflow failures and delays. GitHub is focusing on minimizing critical dependencies on external providers to enhance service resilience.
Future Mitigation Strategies
In response to these incidents, GitHub is taking steps to improve its infrastructure and processes. Enhancements to network device repair validation, cloud resource management, and critical path dependency reduction are among the measures being implemented to prevent future disruptions.
