Powweb was an OK host, one of my least favorites but not bad enough for me to move my sites away. Recently they were bought out by Endurance International. I am really having problems with Endurance. They broke every one of my databases when they migrated my site from the old Powweb servers to their own hardware. So far they've fixed two of them, which leaves big chunks of my site not working. I haven't heard from support in 3 days. My advice is to avoid Endurance and any company owned or being bought by Endurance.
Powweb is TERRIBLE. I had the WORST experience with them. So much downtime, slow loading, etc... I was so happy when I finally moved my websites out of powweb. For your info, lunarpages.com is a much better host.
I like Bluehost although I can't say they don't have any downtime. Powweb was fine in terms of uptime / downtime. It's their mail servers and customer service that I ahve problems with. These days it's mostly customer service. I agve up on trying to use their webmail. I'm maybe giving up on their customer service now too. I just got someone on live chat. Let's see if they can fix the problems they caused.
Powweb is terrible indeed ive been through so many hosts its rediculous lol but i know nopw whos good
