Does anyone use this site much? Has something happened to reduce their visibility? 

I've noticed multiple networks that had massive drops in peerings on or around March 11, 2017. AS5650 went from 66 to 12. AS53828 went from 436 to 19. PCH's AS3856 looking glass still reports adjacencies to both of those ASes. AS3856 went from 183 adjacencies to 113 that same day (and didn't bounce back). It seems rather unlikely that PCH would lose that much, given that their goal is to collect route table information. Even more odd that those two ASNs would also lose a ton of peers the same day.
