I am trying to troubleshoot the issue with our mirror. We noticed that on https://mirror-status.centos.org we have a "no time" status. I've checked and our script is syncing properly. As of this email, TIME and timestamp.txt are both reporting May 20, 2021 17:44 (https://mirror.nodespace.net/centos/).
What would be causing this? I couldn't really find any useful information searching the mailing list.
