Very nice set up. I wonder how much the average # of daily unique visitors is and bandwidth usage.

The contact details can be found in the whois lookup. The "admin email" should forward all legitimate mail to the right person.

I'll give you a good idea that I haven't had time to implement and would like to see created. Many people want to run a few full nodes 24/7 to help support the network, or maybe roll out their own Electrum server, but some of these people don't have the technical knowledge to get bitcoind running on a VPS. Why not make this easier? A cloud platform for automatically deploying X amount of full nodes would be great. You could modify bitcoind settings in a nice user friendly web interface.

Make it really simple and cheap. Also ensure that you allow root access to the server so that more adventurous users can play with it.
