I'm honestly not sure how that would work. I'm thinking that if they threw up a new server and suddenly redirected the eShop (for example) to that server, and had that server check a file other than version.bin that 5.5.0 included... We obviously wouldn't have that new server blocked, so those people would get updated. Probable: no. Possible: I think?So if they add even one new server, every one is screwed except for those who only host locally?
It's all a game of cat and mouse.
