Starting 7 hours ago the Windows jumbo builder turned purple and seems unable to get past the bot_update step.

The only thing looking like an error is
===Running git.bat cat-file -e d58b508a28d4b5beb82e6931a2b78080900d32fc ===
In directory: E:\\b\\c\\git\chromium.googlesource.com-chromium-src
===Failed in 0.0 mins of git.bat cat-file -e d58b508a28d4b5beb82e6931a2b78080900d32fc ===

The step fails in roughly 45 minutes so I wonder if it's rather some kind of timeout.
