Patterns by day of the week would also be interesting. My entirely subjective observation is that there are fewer people around on a Saturday night.

I'm pretty sure there actually are fewer people around.

I say this because there used to be a graph of number of web requests at: http://wikimedia.org/stats/live/org.wikimedia.all.squid.requests-hits.html

The Internet Archive has a picture-less cache of it here: http://web.archive.org/web/*/http://wikimedia.org/stats/live/org.wikimedia.a...

*However* it does not have the images, which were the useful bits.... so you'll probably just have to make do of my summary of them.

Basically what that graphs showed was: * Oscillating within a day, presumably to reflect peak times / off peak times for the US and Europe, with peak load presumably falling in the overlap of business hours between the two. * Varying within a week. Saturday and Sunday were substantially quieter. Most of the weekdays were fairly similar, but Monday was a little bit quieter than the rest (people coping with the Monday work rush?), whilst Wednesday was the busiest day of all (work rush partially coped with?), and Friday was a little bit quieter (thinking about the weekend?).

Hope that helps.

All the best, Nick.
