[tor-relays] bridge usage-panel behavior

[eliaz]

Over the last week or so my bridge usage has been zero, whereas
previously it would show clients for at least a few and usually many
countries.  The only exception is China, which comes up well within an
hour of enabling the bridge.  Usually the usage display stops at 1-8,
but sometimes it shows continuing Chinese use. The bandwidth graph
sometimes shows high, but not extraordinary, traffic. Usually it's
quiet, and there's been no filling-up of the bandwidth.

At a machine running through a different ISP, I logged on as a client
looking to use my bridge address.  As expected, when I got home I saw
that the bridge usage registered USA 1-8 as well as the usual China 1-x.
 From this experiment I gather at least that my setup is working fine.

So I'm wondering if the Chinese client(s) is/are inhibiting other
contacts, and if so, if this apparent locking onto China is a network
glitch or intentional interference.  As the first step I thought I'd ask
here: Has anyone else noticed an apparent locking of China (or some
other country) in your usage panel? - Thanks, eli
