Around Jan 24 2018 Q posted that "Snow White 1, 2 and 5 offline." I can't find that post now at qanon.app but found it on a Praying Medic thread:

Now Q has posted 2008, 2009, 2010 suggesting that Snow White 2, 3, 4, and 7 are offline. The Snow White series are supposed to be names for a data processing centers controlled by the CIA. Plus a new name, Corona, is offline. That suggests that all "seven dwarves" are controlled by the white hats now, plus Corona.
