True...I did try 4.2.2.2 / 8.8.8.8 and some local ones here. All looked fine.

I sent queries from 270+ different locations for the domains you mentioned off-list and I didn't see any 
inconsistencies. The persistent host-caching/browser-caching theories seem like your best bet (or my 270+ locations 
weren't sufficiently diverse to catch a stale zone being served by an anycast authority server).
