Rich-snippets star ratings updated on review sites?

[sauce]

Has anyone noticed since last night Google is no longer showing the aggregateRating & stars rich snippet for a lot of independent review sites. I've tested on over 10 different connections & PC's throughout the US.

It looks like Amazon even lost theirs... seems the sites that still have them are Google partners like TrustPilot, ResellerRatings, & the BB.

There was a 14.5% drop in review snippets yesterday according to Mozcast. Perhaps this would explain the behaviour you saw, e.g. if a competitor was appearing in those snippets and was then temporarily gone?
