On a side notice I notice all images on mobile are missing a cache expiration - is that intended? Also have we considered adding a header Cache-Control: public to them?
This historically has been due to upstream caches not respecting purges and our ops team wanting to keep TTL's as low as possible. We can take it up to the ops list if we want to know more
Is mobile different in this? Just this week I stumbled upon https://bugzilla.wikimedia.org/show_bug.cgi?id=17577 which is quite depressing.
