Top notch customer service. Doesn't matter if it's 3 a.m. I can reach them by phone. Had my first hard drive failure in the past 10 years (only hardware failure this whole time) and I had a new hard drive installed within an hour and I was back up and running.
Great hardware, fast uplink, I personally have unmetered bandwidth which is available at a decent rate. Are they the cheapest? No. But I swear by them and will never use anyone else as long as they keep up the standards that I have been spoiled with.
