Between 15:05 UTC and 16:25 UTC, GitHub API services experienced degraded availability due to sporadic authentication failures affecting approximately 9% of requests. Customers experienced intermittent "logged out" behavior as erroneous 401 responses triggered repeated authentication flows in app integrations. Affected requests also experienced approximately 800ms of additional latency. <br /><br />A memcached proxy service rollout to our internal API infrastructure caused our authentication s
