We use tobie's ua-parser, which should indeed hit a slightly wider range of
tablets and would explain some of that 5%. We should probably have a
different conversation with ops about trying to rebalance the varnish
tablet identification (I've seen the request logs, and that won't catch all
of the tablets).
Re the drop - it's actually the mid-week drop (mobile devices, tablets
included, gain a chunk of our user share on weekends). The script is set to
loop every Friday, so there'll be additional data this time next week which
should allow us to see if the percentages later as, e.g, ISP-side caching
changes.

I wonder how much of these numbers - tablets on mobile
site before the
switchover and on desktop site after it - are due to discrepancies in
tablet detection between analytics and varnish. Varnishes used to detect
them by matching user-agent
against (iPad|Android.3|(?i)tablet|PlayBook|Wii) - how does analytics do
that?

Good news, everyone!
Oliver ran some stats for us on where tablet users were landing (desktop
view or mobile view) a few days before and after the tablet redirect on
Tuesday:
Before the redirect, *13% of pageviews from tablets were hitting the
mobile site*, meaning a non-trivial chunk of users had opted into the
mobile experience even before we were serving it to them as the default.
After the redirect, *95% of pageviews from tablets were hitting the
mobile site*, meaning a fairly small number of users are opting out of
the mobile experience we're serving – smaller than the number of people who
were opting out of the desktop experience before the redirect :)
(Note that the total pageview numbers haven't changed significantly – the
slightly downward trendline in the past few days just reflects the normal
dip we observe toward the end of every week.)
So, tl;dr, it looks like we're serving the needs of the majority of our
users. Graph below, courtesy of our beloved British data analyst/road
warrior. We'll continue to monitor these numbers, of course, but the early
results look good – nice work, team!
