Comment (by starlight):
Issue arrived, EDT:
Jun 1 08:04:48 Tor[]: Our directory information is no longer up-to-date
enough. . .
Jun 1 08:04:48 Tor[]: I learned some more directory information. . .
Jun 1 08:04:48 Tor[]: We now have enough directory information to build
circuits.
Provided debug log off-ticket due to sensitive content and difficulty of
obfuscation. Will provide to any interested dev.
Looking it over, seems to me the authorities prepare consensus diff
documents a couple of times each hour and about 50 or so generally arrive.
Appears some descriptors are overlooked (rather odd odd, perhaps a bug),
and curiously the handful of missing descriptors contains one of the
relay's guard nodes about once a day. The relay requests the missing/out-
of-date descriptors which arrive shortly and repair the deficit. What's
strange is after performing DROPGUARDS it kept happening, implying that a
significant percentage of guards fall into the "overlooked" group any
given day. This is casual observation and could be quite wrong--did not
delve into it deeply.
