Often mentionned as the #1 hoster, we have at Aplus.net the worst hosting we ever had. Both servers we have show unbelievable downtimes. We have regularly "switch" issues (says Aplus...) that put the server entirely down. Several times a day, the server does not answer for a few minutes, then comes online again, without noticing anything on the server side (verified on 3 servers total). Two times, the servers have been electrically switched off for "migration" without having been warned. So yes, the servers have been switched off while running big database transactions. Nice.
Summary : good hardware, but VERY BAD connectivity. Pretty bad support.
