It's always DNS, should I complain? (self.selfhosted)

Hi,

What to do if the domain name of one of my webserver, that me and some lab members use for work related stuff, is no longer resolved by our university DNS? When I first noticed it, I could see no resolution at all while now the domain resolves to a wrong IP. The site can be normally reached on any other network so there is no problem on my side I think.

Should I just wait (now more than 24 hours) or should I try anything? I am entitled to complain to our IT even though the issue is only with this not-really-professional FreeDNS subdomain?

EDIT: apparently some automatism marked this domain as malicious (absolutely it is not, not willingly and not compromised) and somehow DNS resolves to CNAME sinkhole.paloaltonetworks.com.

Thanks for the detailed answer, a lot of suggestions are great but unfortunately a bit unpractical. Changing etc/hosts is at the moment the only think working and if the issue is not fixed soon I will suggest to the users that are willing to do so. I would not go as far as asking people to install VPNs and I am pretty sure that buildin a rogue wifi/LAN network will be against any corporate policy and I will be fired :D
