I'm curious about the peaks and troughs in the graph. It seems the graph reaches a peak every week, does anyone know a reason for this?

Hehe this was an exercise question at my university. Look at the peaks again, zoomed in on a week, and you'll see that it's always on the weekend.

This most likely means that more people have IPv6 connections at home (weekend), than they do at their work place (throughout the week).

You'll notice the same pattern on browser usage graphs - IE peaks during working hours, every other browser peaks on weekends and evenings.

Weekends. More home users have IPv6 than business users. Comcast and Time Warner are both pretty far along in their IPv6-availability rollout.

(You can also check last Christmas, where there's a bit of an extended peak.)
