As fate would have it, we lost 2/4 bandwidth authorites right around
when you started this experiment. I've had the bandwidth value of 1M
for blutmagie in the consensus for the past 4-6 hours or so.

You should see the results of this change already on blutmaggie,
unless the source of the load is due to either clients older than
0.2.1.x, or some other form of non-standard tor client or DoS attack.
