Auth issue impacted GitHub APIs and some Slack and Teams subscriptions
Hacker News (AI keywords)·3 days ago·Incident
GitHub resolved an incident on June 5, 2026 involving incorrect authorization failures for some authenticated requests.
During 14:49-16:45 UTC, a small number of endpoints saw a 1-2% increase in 4xx responses, while most requests completed normally.
The issue was tied to a recently enabled feature flag, which GitHub disabled; affected Slack and Teams subscriptions were later restored.
