You know, that makes sense for a corporate network. They have an extremely aggressive firewall on the academic campus, which is how it should be.
However, they have failed to provide isolated networks for the research labs which just need it for even downloading LLMs (they have banned huggingface!).
Moreover, a hostel is residential. They should provide either the option of getting an external connection (which I would happily do!) or provide a means of non-stupid internet which they aren't.
