I am their customer since March 2010, it all started with a server down, difficult to repair and my previous server management company simply could not handle the issue, I started a thread at webhostingtalk and 24x7 people suggested a solution, I hired them and since then I never look back, months and months pass that I never need them, their work behind the scenes is enough to keep everything going well, sometimes there is an emergency, like yesterday, I was without internet for 3 days! and one server went down, working through phone messages 24x7 Chief worked with me to contact the datacenter repair the issue and fix everything, including ready to contact my customers with an update while I was offline and my other service personnel were out of the loop.
From the very bottom of my heart, Thank you very much.
