The
download.linuxaudio.org alone has served 2.3TB
(yes, Terabytes! :-)
since January 2007, with almost 600GB in May alone. Out of 7500 unique
visitors who actually bothered to visit the site (this is a download
repository so not much to see there), over 70% have actually bookmarked it
(go figure). FYI
download.linuxaudio.org (apart from software projects)
mirrors ubuntu studio, 64studio, and jacklab distributions.
Overall, this server appears to serve ~50GB/day across all sites and in 8
days (since cumulative tracking was implemented) it has served little over
400GB with an average of 35-40,000 hits a day.
