Deploy fail: Too long with no output (exceeded 10m0s): context deadline exceeded

Starting Oct 13, 2023 we started seeing these “context deadline exceeded” errors while attempting to deploy to Netlify. We’ve isolated the problem to the CircleCI environment – the Netlify deploy succeeds on all other platforms. Historically, these deploy uploads have been working for years in our CI pipeline and generally take less than 10 seconds.

What platform permissions might’ve changed on Friday the 13th that are causing these uploads to suddenly fail?
