Hi all, I'm investigating an issue with GitHub Actions runners having issues connecting to www.cygwin.com: https://github.com/actions/virtual-environments/issues/698
I worked with the Azure DNS team and in this comment <https://github.com/actions/virtual-environments/issues/698#issuecomment-628284472> I detail what we believe to be the likely issue. Summarized: www.cygwin.com is CNAME'd to server2.sourceware.org server2.sourceware.org is an NS server for sourceware.org We believe that the above configuration is triggering a bug in WinDNS that is causing intermittent DNS resolution failures. I don't have an ETA for resolution from the Azure DNS team, and internally I'm translating that to be on the order of months before we see a fix. In order to resolve this faster for customers, I'm reaching out to see what options we have for updating the DNS records that are triggering this bug. Is there a change you can make to either www.cygwin.com or server2.sourceware.org DNS such that it doesn't have this recursive reference issue? Some options are to replace the CNAME with an A record, or to use something like ns2.sourceware.org for the NS record instead of server2.sourceware.org which is being used for cygwin's A record reference.
