I'm talking of 1000 users on the end of a 1GE, not 50,000. I don't think 
either of these scenarios are worrying.

300MB takes <3seconds on 1GE or 30 seconds on 100M. I don't think those 
kinds of events will have an appreciable effect on the platform here. An 
album is what, 100MB? A 5min HD youtube video is going to be a similar 
size. Also too small to care about. These kinds of things don't get 
worse in high speed, they get easier.

Same with patch tuesday, I think even a Win7 SP1-like release wouldn't 
cause major headaches, as streaming SD TV for an hour is more bandwidth 
than SP1 (nevermind HD).

I'm more interested in the levels of traffic that we will see consistently.
