It's always DNS, should I complain?

Sounds like your university is using a Palo Alto Next Gen Firewall which is intercepting DNS requests and responding with the sinkhole FQDN for anything they deem malicious or suspicious. You can try to override this with DNS over HTTPS but they may also be blocking that. Standard security stuff. You can also probably try to open an IT ticket and request that they whitelist the domain.
So it seems. Do you think this was from the detected user activity? A colleague reported it was using it and it stopped working from one second to the next. Maybe some of his traffic looked suspicious? I am opening a ticket in any case today.
That is possible as well. Those firewalls are capable of packet inspection. If you are using personal devices it won't be able to see much if you are using encryption in transit but if you are using University provided machines there is a good chance they can inspect all the data you are sending and receiving.
