Hi there, thanks for the props, and glad you're using Mibbit

For the curious, the Mibbit widget backend currently runs on a single 1.4GB VPS, and handles between 500 and 1,500 HTTP reqs / second

and it's currently at 260% of its bandwidth quota - about 2TB
Linode have been an awesome host for Mibbit.
Out of curiosity, since the price difference between the Linode 1440 and Linode 2880 is the same as the cost of the extra bandwidth ($80 difference, 800GB extra bandwidth), why do you have the 1440 and not the 2880?
It would cost you nothing to migrate to a 2880 since your bandwidth seems to be well above 1600GB, and you'd double your RAM, disk, and CPU allotments.
