Comment (by boklm):

 In version 6.5 which was published on January 24, with ticket #19481 we
 changed the update URL from
 https://www.torproject.org/dist/torbrowser/update_2/ to
 https://aus1.torproject.org/dist/torbrowser/update_2/. The
 `www.torproject.org/dist/` URL was redirected to `dist.torproject.org`
 which then returned the result, whereas with the `aus1.torpoject.org` URL
 the result is returned directly without a redirect. A possible explanation
 for the drop from 2017-01-24 is that the update ping were counted twice
 before the URL change because of the redirect.

 In version 6.5.2 we changed the `update_2` part in the URL to `update_3`,
 with ticket #19316. Initially metrics didn't count the `update_3` requests
 as update pings, so this caused a drop in the update pings graph, but this
 has now been fixed. What we can see now is an increase in the update pings
 around the 4th and 5th of April, but it does not seem related to the URL
 change as there was no release around that time. I don't know the reason
 for this increase in update pings.
