Hi,
For the past several days the number of relays measured by my bwuath (whose data is given my maatuska) have been slowly declining. Originally I had an alert when it was below 8800, a few days I noticed it going below that. By today it's decreased to below 8700 to 8664.
It's not the lowest bwauth measuring, but I don't see anything obviously wrong with my bwauth to indicate the decline. (The number I mentioned is number of lines in the bwscan.V3BandwidthsFile file, not the measured relays that make it into the consensus - but the comparison I just made did use the consensus count.)
If "past several days" matches with "since 2016-03-24", then I would not be surprised if the Global Frag Networks group [1] caused this - at least partially.
Many of the unmeasured relays are from the global frag group (since they just joined the network)

Many new relays means a rise in unmeasured relays and if at the same time a few relays leave then that would explain the decline even for absolute values.

Interesting. Perhaps the arrival of bunches of new relays is a trigger for or exacerbates the bug where BWauths skip measurements, scanner/band #1 esp.
