Cannot Connect to Server, ugh.

I'm hoping it means an update, ideally a level update. The fact it's intermittent and some can get on, while others can't, may be a sign of them taking some servers offline to upload the data for whatever additions/changes/fixes the theorized update contains. I assume it's being added to the servers, and will kick in at a certain time.

What time do updates normally hit? Is there a set time, or is it just random? I usually notice them only after I get a push notification that there's new stuff, since I normally play at night anyway.

Wonder if (assuming there is an update) it'll be an in-game update or require an App Store download.
