Cacheboy is currently pushing a good 800-1200mbit of firefox 3.6.4 updates. It has about 6% of the total mozilla mirror weight so I predict that there's currently around 16 gigabits of total mozilla updates going out.
Lusca is holding up fine - a single process happily pushed ~ 400mbit on some hosts during the initial peak. I'd obviously like to be able to push a lot more than that but I'm still doing baby steps in the Lusca performance department.
