After I moved from (spit) mediatemple to MediaLayer last April, I wrote a glowing one-month review (http://www.webhostingtalk.com/showthread.php?t=693744). So 10 months on, what is it like?
Well, rather boringly, I don't have much to add to my original review, since it's still as awesome as it was then. I tend to forget most of the time that I'm even paying for a hosting service, because it's just there, rock-solid, serving my sites stupidly fast. At least it's more exciting at other hosts when you're constantly having to manage one crisis after another.
It's true that MediaLayer are more expensive than many other hosts, but they're a bargain at the price.
MediaLayer's public Hyperspin report (http://www.hyperspin.com/publicreport/35969/23008) is currently showing better than four-nines uptime on all servers. 'Nuff said. Great company. Happy customer. That's all.
