[tor-project] Diversifying Bandwidth Measurement

Dear teor,

First, my apologies!  We've had some issues with Cogent as a peer of
late, though I didn't realize it was impacting our Tor efforts.  Ugh.

Second, I'm going to turn this over to the Engineering team here.  We
will shift things about for the bwauth.torproject.org server to
provide better connectivity.  That may take a bit, but it will be a
priority.

Third, we can easily stand up something on 38.229.70.2.  Was this one
of your servers, or one of ours?  Do you recall?

I am about to jump on a plane to London, so I'll be offline for a few
hours.  I'll ensure this is handed-off to someone who remains in
contact with you, teor.

Again my apologies, and we're on it!

Thank you!
Rob.
