 > How did you fix the first problem?

 See the [https://gitweb.torproject.org/metrics-web.git/commitdiff/f00cfbe
 commit message] for a description of the fix.

 No.  I only fixed ''direct users'' graphs for ''single'' countries, not
 bridge users from all countries.  The 0 (which is actually a 184) comes
 from too few bridges reporting statistics.  We should interrupt that line
 if there are too few reporting bridges.  The much better fix, though, is
 to work on #5807 for real bridge usage statistics.

 > Are problems with statistics gathering in the network happening
 frequently?

 With bridges, somewhat, yes.  We have 1--2 events when the tor process on
 Tonga fails, Tonga fails to copy over descriptors to yatei, or something
 else happens.  We have deployed some checks to notice these problems
 early, but it still happens every now and then.

 With relays, rather infrequently.
