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.

Git itself doesn't make any attempt to access those systems unless it's
configured to do so (e.g. a remote is set up to talk to those systems
and fetch or pull is used).

It's possible that you're using a distribution package that performs
this behavior, say, to check for updates.  I'd recommend that you
contact the distributor, which in this case might be Git for Windows,
and see if they can tell you more about what's going on.  The URL for
that project is at https://github.com/git-for-windows/git.


The normal Git for Windows install includes an option to check for updates at a suitable rate. Maybe you are hitting that. It can be switched off.
