Did you ever find an answer here?

What have you analysed?
Have you tried any config changes?

Can you tell us which directory authorities are measuring your relays lower
than they were before?

The most likely scenarios are:
* Routing changes between your relays and the bandwidth authorities
* The Torflow to sbws transition
* Did you upgrade your tor version?
  Most of the network upgraded to tor 0.4.1 and 0.4.2 recently:

Did the consensus weight drop first, or did the observed bandwidth drop first?

You've probably read this wiki page before, but just in case:
