What's with all the email downtime - going into the third week now

I am going into the third week of constant and annoying downtime with email. I switched from POP to IMAP and it is better but still up and down all day long. Webmail is also tracking this. It's down when POP/IMAP is down. An occasional outage happens but this happens all day long making my Cox email accounts almost useless. I've had to setup Gmail accounts just to have something that works. What gives?
