It's always DNS, should I complain?

Submitted ⁨⁨1⁩ ⁨year⁩ ago⁩ by ⁨aesir@lemmy.world⁩ to ⁨selfhosted@lemmy.world⁩

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 got reported it I could see no resolution at all while now it 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?

I would migrate the domain. Don’t bother with flakey services. Cloudflare free tier can do some amazing things.

In the meantime set it in your host file to the correct IP to get by.

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.

Cloudflare tunnel is the easy solution here. It’ll cost you a couple bucks a year for a domain name but you’ll have no more DNS issues.

This may come down to details of their policies and how they interact and support each department. If it’s for your official work, and I’d say start with a ticket and if they resist then push it up the flag pole and don’t stop. (Assuming you’re not one,) Your PI ought to fight like hell to make sure their employees can do their jobs, and the chair fight to make sure their researchers can run their labs, and the dean much the same, but throwing heavier punches each step up. Really shouldn’t get to that point, but if you can’t do your job, rattle the cages until you can.
