After I saw about 630 viewers on Leo Laporte’s U-Stream of his Tech Guy show it went down. I think the UStream server did pretty well. Apparently the local one will take 1000 concurrent viewers - so now now the ’server is full’. I hear that there is a backup for this, using a dedicated CDN provider. If you didn’t realise it, much of Chris Pirillo’s U-Stream output from Podcast Hotel has been coming form the dedicated service.
Here’s how it went down.
(BTW: Someone asked Leo to put the keyboard on his head - so he did 
)
I’m sure that Brad from U-Stream has more to worry about at this time - I hear a baby is imminent! Good luck with EVERYTHING!!! 
It must have been the “keyboard on head” moment. The Digg kids got too excited.

Ustream bows to the power of Digg! We’re sending the guys out to buy more servers.
