HostGator

Been with HostGator for many years, but they have gone downhill recently. They guarantee 99.9% uptime, but don't accept 3rd party logs (e.g., Pingdom) and don't monitor themselves. So you cannot prove anything. By the time you reach someone on chat, 20min+, the site is back up and they don't want to know. Complain and they blame your browser or some other bull. Its not just the web site either. Emails would also not be sent or received. I'd go to send an important email, last thing of the day, only to find it didn't send. I was giving them the benefit of the doubt, but after reading other reviews here I'll be jumping ship very soon.
