This reminds me of https://issues.guix.gnu.org/30290. Perhaps if we can fix that one it'd make this one go away too?. I was thinking of having a simple mean to reduce the request attempts on servers down for a long while, such as entering dead periods (breaks): "I've tried X times, it doesn't respond, I give up for the next Y minutes"; allowing for X and Y to be configured via the <guix-publish-configuration> record. Do you think this would help? Maxim
