I didn't have any problems today... I even tested it out. I did a few days ago when there was that RIM maintenance outage, but that has been cleared up.

I do think there was a little bit of a gmail delay yesterday. And, since the outage, I've been getting some emails 2 and 3 times each. Hoping not to see that again today.
it was fixed with a removal of gmail from the BIS site, then within gmail, i shut off imap, turned it back on... then added gmail again to BIS... back to instant PUSH IMAP...
