(Xbox 360) Firmware Update 5/19/11 Canceled?

Was just on 8PM CDT here in the states was not prompted to do an update I booted up a game as well still nothing?

Uh, should have. I got the update this afternoon as did all of my friends.

I could go to COD Black Ops Multiplayer as well weird?

I was hoping it would totally and completely wreck my system. But darn it all, it didn't.

Looks like it's based on a roll out system that will occur up till the 30th

I have no source or link though just here say
