Upcoming Disruption of Service Impacting Unreal Engine Users on GitHub

Hey team! I’m getting these over and over again while trying to run Setup.bat on ue5-main branch and on commit 7102abc:

Just once, Setup.bat run without errors on with a branch created from commit (7102abc). I had to set it up on another PC and it never worked. It’s not working on the original PC anymore.

The hash at the end of the URL varies almost on every attempt to run Setup.bat. I tried navigating to some of the URLs on the browser and they either worked or returned an access denied error.

It’s been like this since yesterday, August 16th.
