My least favorite web hosting provider is Cirtex Hosting.

During my time with them, the support was sub-par and their servers were always under-fire. When I finally had enough with them, I moved off to another web hosting company, but leaving them was a hassle in itself. The support team seemed clingy on trying to keep me, I only managed to cancel my web hosting package when I agreed to let them manage my domain name. A mistake, since they later decided to not issue me an invoice, and not allow see more me to pay for the renewal. They also would not answer any of my support requests.

My favorite web hosting provider is tied with MM Hosting and Media Temple.

I'll write about them some other time. The Cirtex Hosting write-up has left me drained.
