what was that site about ?

Looks like the UVA online judge system, a practice website for ACM ICPC competition questions.

Sucks if they lost data, a lot of people are very proud of their account history on there. It says closed for "a few days" though, not forever.

ACM online practice site. It's huge, used by the competitors all around the world.
