There seems to be some confusion between EA’s Online Service Updates page — which lists August 28th as the date on which Ultima Forever will be taken offline — and the Ultima Forever Twitter account (and forums):

Hopefully the 29th is the correct date…because there’s something I want to propose.

I think we should all — or as many of us as are able, given that not everyone has an iOS device at their disposal — take time on the 28th to play Ultima Forever for as long as possible. We should make August 28th into “Ultima Forever Day”.

Certainly, that’s what I’ll be attempting to do; I’ll be logging as many hours in the game as possible…in addition to posting a bunch of art from the game that I have at my disposal. And I would invite everyone who can access the game to join me therein. We’ll wander through Britannia once or twice more, do some dungeon runs, and spend every last key in our coffers.

And if the game gets shut down on the 28th…well, maybe we’ll be lucky enough to be in the middle of something in-game when the signal flickers out. We can hope, at least.
