Git Slowness on Windows w/o Internet

Hello,

Wanted to bring to your attention an issue that we discovered on our
Windows Jenkins nodes with git scm installed (git.exe). Our Jenkins
servers don't have Internet access. It appears that git.exe is trying
to connect to various Cloudflare and Akamai CDN instances over the
Internet when it first runs and it keeps trying to connect to these
CDNs every git.exe execution until it makes a successful attempt. See
the screenshot attached with the details.

Enabling Internet access via proxy fixes the issue and git.exe
continues to work fast on the next attempts to run git.exe

Is there any configuration setting that can disable this git's
behavior or is there any other workaround without allowing Internet
access? Otherwise, every git command run on a server without the
Internet takes about 30 seconds to complete.

Please advise.

Thanks,
Peter
