Comment (by starlight):

 Stand by it; still true:

 "BWS longclaw never recognized the change"

 What the scanner did was--after the protracted delay of five days--detect
 lower available bandwidth which resulted as a consequence of the reduced
 configured maximum, because BandwidthBurst was used to establish it rather
 than MaxAdvertisedBandwidth.

 The raw data is all here https://collector.torproject.org/archive/relay-
 descriptors/bandwidths/

 A one-line perl script extracted the attachment data such that it is
 comprehensible in the context of the issue.
