From Rob (comments and formatting mine):
"The bandwidth usage (for alone jumped from about 300GB to 1.3TB (a month) in the past 6 months. Considering that,,, (and about 5 other sites) all run on 2 web servers and 1 db server I think it held up pretty good :)"

Definitely a good commercial for the pipes and infrastructure team over at OrcsWeb as well.

OK, we really need to get a fund going to get more servers in place for everyone. I volunteer my Paypal account for donations.
