[tor-relays] entry guard interference?

[starlight.2015q1 at binnacle.cx]

Last bit of info. . .

I realized that the two other events
mentioned earlier where the hard-configured
guards were unreachable were the result
of local Internet connectivity outages
--had slipped my mind when writing that
message.

So the 30 minutes (almost exactly) of
guard unreachabllity was a unique
event following the hard-coding of the
guard nodes.  As mentioned, I've seen
the guards change-out entirely
before adding the EntryNodes configuration
despite having "GuardLifetime 18 months"
set.

Finally I checked the consensus votes
for the three hours surrounding the
event and both guards were in the
consensus at all times and without
interruption.
