Do your logs go back 2 years? How much data is that?
I know. Maybe everyone could go to the DoJ site to read the several-hundred-page pdf of this proposal and all its supporting arguments. Then go back again every couple of hours to see if there have been any updates. Maybe do some research while there; you know: searches, a couple wget's to make sure you didn't miss anything, stuff like that. Then the DoJ webmasters could say how big the logfiles got, and what it would take to store two years' worth of that traffic.
