I was once responsible for a student house (we don’t have dorms in the US sense, this is the closest we have) and I have similar experiences but less extreme. My favourite was when I had forgotten to configure DHCP filtering and someone plugged in a router the wrong way so it started offering DHCP (that didn’t work) to everyone in the building, in a race with our upstream ISP.
Also, the times rats got into the networking room and ate random cables. I should add the network was built by volunteer students in the ‘90s.
