3 of the last 15 builds have succeeded. There's no relevant changes to our docs, and we're seeing some docs now that were added a couple of weeks ago. Build 5896563 is the most recent success. The failures, like build 5899555, have no useful feedback data.

The git checkout isn't in the successful build output, so it may be part of the pre-build and failing. We recently migrated our locale data to a submodule (mdn/kuma#4338), so this change may have an impact on the checkout operation.

Though I'm not exactly certain why the problem is seemingly non-deterministic, I believe I've addressed this issue with #3073.

As the most of the build are passing, I think this is fixed by the patch addressed in #3073

Builds are reliable again, thanks for the fix!
