GitHub acknowledged that this was an incident and resolved it.

We have identified the source of this incident and are working on remediation.

Since approximately 9:30 AM PT, a portion of analysis builds have been failing during the tool-installation step, with errors like "Error installing tool …" in the build log. We've traced this to an upstream disruption affecting downloads of release assets from GitHub — the archives our builds fetch to install linters and language runtimes.

The disruption is intermittent: during failure bursts roughly 1 in 8 builds fails, and between bursts builds complete normally. We have escalated it to GitHub.

What you can do: re-running a failed build will usually succeed, though a retry may still hit a failure window while the disruption continues. No action is needed for builds that completed successfully.

Coverage uploads and processing, qlty.sh, and the API are unaffected. We're monitoring failure rates continuously and will post an update when the disruption clears.
