We tried to use aplus.net as a dedicated server host, but cancelled service after only a month and a half.

Tech support is extremely rude (that is, if/when they the phone). If you have to leave a voicemail, don't bother. The only way they return your calls is if you threaten service cancellation, and even that takes several days.

Also, if you plan on hosting a site with them, forget about FTPing your files to them (especially files over 2MB). It doesn't work. Upload speeds are horrible. Never tried downloading, as I could never upload my site to test.

Also, their quality control is terrible. One of my servers arrived missing a processor. Another showed up without IIS and without the windows cab files.
