["Slutz, Donald Christopher" <dslutz@xxxxxxxxxxx>]

I just got off the phone with EarthLink.  A rack can have 2x 30A/208 power.
Looks like 1 30A/208 would fit.  We are limited to 24A steady draw.  So
24*208 is less than 27*200, but if 44 for many of the servers is right;
we should be fine (more cost for 2x 30A).

On the network bandwidth cost, they have changed the way they handle this.
They now use "95th percentile bandwidth metering". I found


http://www.semaphore.com/blog/2011/04/04/95th-percentile-bandwidth-metering-explained-and-analyzed

to be an easy read.  Still have no idea what our network bandwidth should
be.  For now I have it at 2Mbps.
