How GitHub uses GitHub Actions and Actions larger runners to build and test GitHub.com

As we continue to expand the infrastructure that powers GitHub, we want to make everyone aware of some

to 192.30.255.255
. The warning message looks like this:Warning: Permanently added the RSA host key for IP address '$IP' to the list of known hosts.
Thanks for your patience and continued support as we work to make GitHub faster and more reliable!
