It looks like your node got the "Guard" status - google around for what that
means, or wait for someone to explain. When that happens, your traffic drops
significantly, and it can take weeks or months till it recovers to initial
levels, if it ever will at all.

Personally I don't agree with the theory behind "Guards", and it is highly
annoying that there is no way to prevent nodes from becoming Guard. The only
way to drop that status seems to be nuking the whole /var/lib/tor/keys/
directory and restarting tor; this has the same effect as if you have just
started a new node. Needs to be done every couple of weeks, but getting back
to expected traffic levels takes at most 3-5 hours after that each time.

With respect,
