I've been a customer with APlus since year 2003, so about 7 years now.
I tried APlus in 2003 because they were CNet's recommended choice and they were in fact amazing hosting provider back then.
Technical support was really good and the amount of resources you got for the money was far better than any other hosting providers. I don't even think I had major downtime for couple of years. I was so happy that I bought 2 additional accounts with them.

However, everything changed in year 2009 when they were bought out by some company or had change in management. They announced that they will be upgrading their platform for all users and then the nightmare began. They have been nothing but trouble...
Since 2009, their technical support was crappy (they really didn't know what they were talking about) and their billing team was even worse. My websites were either down or mis-configured all of sudden due to their upgrade changes. It took so much longer to get hold of technical support over the phone and they often didn't know what was wrong or simply said it will get better once their upgrade is complete. I ended up cancelling 2 accounts with APlus and didn't even get any refund (per their policy).

I really miss the old, original APlus company. I kept one account with APlus because they do offer very generous resources for the money and I'm basically using their hosting service for the disk space. They also give you multiple website/domain option, which is nice. If you need LOTS of disk space and bandwidth for low price, APlus might be a good choice but I wouldn't use them as my main website because their service and servers are unreliable now.

I was a customer with Aplus for many years. They were responsive to tech support tickets, and there was rarely a need to file any. They were the perfect host, albeit slightly more expensive than some of their competitors. Then, in late 2009, they underwent serious system upgrades. Personally, I think they were bought. After these upgrades, I decided to redesign and relaunch my website and that of another client whom I had recommended to host with APlus. Both accounts had to file support tickets which were responded to slowly and with form letters. Only two sentences in the entire emails differed despite being responses to very different issues! MySQL servers had been outsourced and the Control Panel interface became very slow. The servers now run on a hybrid system of Windows and Linux hosts. Migrating away from them also took quite a while because they held my domain for almost a week past my transfer request. Maybe they've gotten the kinks worked out, but I would enter APlus with extreme caution.
