Contegix Rocks
I've been working a lot with the guys at Contegix lately. They host both sourcebeat.com and virtuas.com as well as Subversion repositories and mail for both. They also host AppFuse's JIRA for free. They sent me the following e-mail this morning:
issues.appfuse.org has been upgraded to JIRA Enterprise 3.2. Total downtime was less than a minute.
Emphasis is mine. Not only do these guys provide excellent hosting, their support is the best I've ever seen. Whenever I send them a support question, they respond in under a minute. It really is a pleasure to work with them.
