Comment (by tom):

 https://ritter.vg/misc/stuff/tor-bwauth-dns-comparison-01.png

 I ran two bwauths, that had no differences between them, and calculated
 the average difference between two sets of relays for each consensus: the
 set of all relays, and the set of relays where the bw measurement was
 above 100 in both bwauths.

 That data (the blue and green lines) are the control.

 Then I changed one bwauth to connect to the final destination using an IP
 address and left the other one connecting using a DNS name. That data is
 the the orange and red lines.

 I don't see much of a difference. So it seems that bwauth measurements
 were not affected by this issue.
