Update 2024: This project has reached its EOL. Sorry if you were using it (I've been told by a few that were). The server and its data will be gone in a few days. I still have the 67 GB backup mentioned in the link above locally on my hard drive. It's not in a replace-and-go format, so you should know what you are doing. Should you need it for a good reason, I might send it to you somehow, then please get in contact.
I won't be keeping the actual DB though, because 500 GB (uncompressed) is just a ridiculous amount of storage.
