Comment(by karsten):

 The problem seems to have stopped around end of 2011, but I still don't
 know why it happened.  I just attached a
 [https://trac.torproject.org/projects/tor/attachment/ticket/3266/missing-
 extra-infos.png visualization] of missing extra-info descriptors and a
 [https://trac.torproject.org/projects/tor/attachment/ticket/3266/missing-
 extra-infos.csv.gz CSV file] containing the raw data behind the graph.
 The graph has a dot for each server descriptor that is referenced from a
 consensus; that dot is black if we also have the referenced extra-info
 descriptor, or red if we don't have it.  Only the top 10 relays by missing
 extra-info descriptors are shown.

 Interesting facts:

  - gabelmoo (F204) failed to publish some of its extra-info descriptors
 from February to April 2011, before it failed to publish almost all of
 them for about a month.

  - Relays E812, CE3D, 39BD, and 1E39 started failing to publish their
 extra-info descriptors in October 2011 for almost two months (or until
 they went offline in case of E812).  Then they suddenly resumed publishing
 them.

  - Relays AD96 and 3372 had short bursts of a few days or a week of not
 publishing their extra-info descriptors.

  - Relays F11E, DEF3, and B47B had a phase in early 2011 when they
 published only some of their extra-info descriptors.  This phase coincides
 with gabelmoo publishing only some of its extra-info descriptors.

 I should say that what we see here might not be a bug in tor, but in
 metrics-db and weasel's directory-archive script.  I'm running out of
 ideas here.
