I owned it. I took a job with our network provider, my partner got the servers back (he invested the money to buy them) and ran it for a while, he wasn't technical enough to maintain it, lost interest, and decide he'd rather stop spending money on datacenter space and the server is now down. I will get the contents of various hosted sites on the server (like heatedebates) soon and give them to the appropriate owners.
The domain, which is still owned by me, was moved to another server when this one was shutdown. It has no content, and I have no immediate plans to get the file hosting service back online. The site was not hacked.
... And your site may have appeared slow because the IP to the 2nd nameserver was removed, causing some DNS lookup timeouts.
