I have worked 10+ years in IT, with companies many of whom you may know but can not name drop.
I am in Houston, Texas so you know you can deal with me on your time if in the states, my cell will be avail to you, but I do ask that I be given ample time to investigate issues properly and thoroughly.
Just to let you know, it takes time to do this, so, I would be monitoring the server for 14 days on this bid to find out what is happening, if it deals with hardware, then that would be your data center.
