I've been with ColoCrossing.com in all of my service locations for over 6 months now, and I would like to say the service is incredible. There has been very little downtime, the only downtime I have ever experienced has been caused by scheduled maintenance which I was notified of at least 24 hours before it took place.
And as many of you know their network in all of their locations are some of the best available.
Support tickets are always answered quickly, even at 4 or 5 AM in the morning.
I recommend ColoCrossing to anyone looking for a quality dedicated server or colocation provider. We colocate with them but I have rented their dedicated servers with equal results.
