According to EagleStatus, separate outages were also recorded at 11:26 AM and 12:12 PM, in addition to the major incident.[EagleStatus] On February 2nd, Actions runners were down for 5 hours, and on February 3rd, 4% of Copilot requests failed.[GitHub Status]
Impact on Development Workflow
GitHub outages lead to CI/CD pipeline disruptions, delayed PR reviews, and paralysis of Webhook-integrated services. If Copilot is also affected, the flow dependent on AI coding tools is also disrupted.
GitHub has stated that it will share a root cause analysis. With three outages in one day, it is highly likely to be an infrastructure issue.
