There's a fascinating side-effect of the Apple Dev Center troubles happening right now: review times are some of the best we've ever seen. I've personally just had 2 app updates accepted in 2 days each, and a brand new app in 3. Take a look at #iosreviewtime, almost everything is coming in between 2 and 4 days, which is virtually unheard of for iOS app reviews.
What's curious about this is the timing: as you're no doubt aware, the Dev Center has not been having a great time of late, but as of this weekend is (mostly) back up.
So how come these review times are so good? All the support staff have nothing else to do while the sysadmins are pulling 18 hour days? Whatever the reason, I'm not complaining.
UPDATE
Good point from the commenters: there will have been fewer new apps appearing since you would have had to have created your profiles before last Thursday, and so more time for app updates and the organised among us.
UPDATE #2
The word on Twitter is that while the reviews are quick, they might be not actually very good, and plenty of crashy apps are getting through. Got a buggy app? Make hay while the sun shines!
