I'm not much of a writer so please excuse this brief review.
I've been with Dotable for 4 months now and I can honestly say that my sites (both database driven) have never performed better. They're on different servers and both are super fast and reliable. I only remember one downtime that was taken care of very quickly.
Support isn't as quick as some of the other huge hosts I have been with. Though I haven't used it in a long time so it's possible Dotable has improved this area. Support tickets are more personal though and that's huge plus. I can't stand those copy/paste responses some companies send.
I've been with around 6 hosts now and Dotable.com is by far the best. Highly recommended.
I'd rather not post my domains here so if a mod needs verification please pm me.
