3. identifiedNov 4, 2026, 03:02 UTC

   Since ~21:40 UTC on Nov 3, GitHub started rejecting the default User-Agent our Git Sync client sends (nanogit/0), so nearly every GitHub-backed repo shows as unhealthy ("not authorized") and syncs are being skipped. Our Engineering team has rolled out a fix to development and validated that the fix works. We will roll out the fix to production shortly and will provide another update.
