I host a couple Community Server sites here and would highly recommend anyone looking for hosting to SERIOUSLY consider reliablesite. I was a bit wary at first because they do not list a phone number but the support provided here is second to none. I had previously tried hosting with another company and it took them a week to fix anything regardless if you called or emailed, here you submit a ticket and things are usually done within an hour.
If you need a large database for your site, top notch support and great pricing then this is the place.
