As we continue to brave incredible load on our server please allow me to use
this opportunity to extend gratitude to those who have generously offered
their time and talents to keep server in working condition (especially given
our limited bandwidth).
So please give a round of applause to Robin Gareus our interim admin,
Burkhard Ritter, our Linuxaudio.org webmaster, and Marc-Olivier Barre our
listserv admin. Without their collective genius our server would be now a
melted pile of goop!
To give you a perspective on just how incredible their accomplishment has
been please consider the following geek stats:
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.

How do you know something like that? Do browsers send a special header
when you go to a site via bookmarks?

FWIW, my guess is that this data is drawn from the originating sites which
is likely not very accurate (if there are none, then the assumption is that
the site is bookmarked).

Either it is bookmarked or the site is accessed directly by typing in
the URL. Though I'm not sure that you always get the address of the
originating in the logs. 70% seems a bit too much...

I'd explain it by the fact the the first attempt (referring eg.
ubuntustudio.org) was denied by our server. Users who actually got a
slot at download.linuxaudio.org kept trying (bookmark, reload).

not a special header for bookmarks, but yes, the browser sends a
"HTTP-referrer" the URL where you come from - similar to cookies. you
can disable sending them fi. with the firefox-webdeveloper "Disable
referrers" menu-option.
awstats (generating our statistics) interprets an empty referrer as
bookmarked URL or URL entered by hand..

well, it's not THAT bad. - referrers from search-engines are more
interesting, than from end-users. and I'm not gonna comment on:
http://stats.linuxaudio.org/awstats.pl?config=www.linuxaudio.org
google-crawlers alone have been downloading 8.44 GB from linuxaudio.org
via HTTP in the last 10 days!!
There are many caveats interpreting HTTP-logs in general and AWstats in
particular eg. the hourly log: the downloads are logged when finished
(not when started - the average ubuntustudio-iso download takes ~12hours
with a 4hour std.deviation - so stats are pretty blurred). partial
downloads are counted as "not-viewed-traffic"; while the request that
eventually completes the download counts as "viewed-traffic" - this
obfuscates the "avg. size" transferred for each file...
The squid-cache that we use to generate "total" stats does not log
special HTTP-headers like the referring URL. so we don't have a total
count here.
Anyway, we still reject about 90% of all requests to the ubuntu-iso to
keep the remaining services up and running - there are avg. 60 simult.
downloads for ISOs sharing a 600kbit/s slot. - PLEASE USE TORRENTS!
I was really amazed at the stats! Given that we only have a 10Mbit/s
uplink. there's > 92.5% utilization in average! kudos to squid-cache.org

PS. the new linuxaudio.org servers will feature mrtg - for the book of
records: linuxaudio.org survived under a sys-load of 66 for about 40
minutes on May 13 2007.
