The problem usually seems to be that we blow past the data caps, so Ramnode shuts it off, then we tell them that the traffic is all internal to the DC on that machine, so they insert coin into the data cap machine. Repeat once for each server near the end of the month, at random intervals. If they could meter traffic that actually left the data center that would be helpful.
