The remote server is having intermittent issues. Sometimes all three servers behind the host are gone, sometimes they block all packages.# nmap -vv cyrus.andrew.cmu.eduStarting Nmap 7.80 (https://nmap.org ) at 2020-06-12 20:52 CESTWarning: Hostname cyrus.andrew.cmu.edu resolves to 3 IPs.

The tests have been disabled, so I understand that the "release blocker" priority is no longer needed. It would be nice to reenable these tests, but I consider that it should not block the next 3.9 release.
