I haven't brought it up with them, no. I didn't think it was a mass issue until last night. I wanted to check with other users before I went to them. Maybe I should have done the opposite.

Have you received a response from qrator? My guess is that they 
dropped a BGP collector session that was advertising garbage 
(modifying AS path to make non-connected ASNs appear connected).

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.
