We use tobie&#39;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&#39;ve seen the request logs, and that won&#39;t catch all of the tablets).<div>
<br></div><div>Re the drop - it&#39;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&#39;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.<span></span><br>

<div dir="ltr">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?</div>

<div><br>

</div><div>Before the redirect, <b>13% of pageviews from tablets were hitting the mobile site</b>, meaning a non-trivial chunk of users had opted into the mobile experience even before we were serving it to them as the default.</div>



<div><br></div><div>After the redirect, <b>95% of pageviews from tablets were hitting the mobile site</b>, meaning a fairly small number of users are opting out of the mobile experience we&#39;re serving – smaller than the number of people who were opting out of the desktop experience before the redirect :)</div>



<div><br></div><div>(Note that the total pageview numbers haven&#39;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.)</div>



<div><br></div><div>So, tl;dr, it looks like we&#39;re serving the needs of the majority of our users. Graph below, courtesy of our beloved British data analyst/road warrior. We&#39;ll continue to monitor these numbers, of course, but the early results look good – nice work, team!</div>
