This is because moria1 is running an experimental patch that drastically cut
down the number of voted HSDir. It has been doing that for a while now. I
can't recall the ticket but this was an attempt a while back to see how much
it would be bad to vote down for the most stable relays on the network to be
HSDir.

Roger can probably explain it better but all in all nothing to worried about
there as it is expected.

Actually, from time to time, you should expect moria1 to behave strangely
sometimes since it is often running alpha code :).

Cheers!
