Hey, thanks PhilB66.
I think a9 is just spreading the word on sightspeed, forum jumping.
But that's some good info there.
I didn't realize there were so many.

The Skype outage is being blamed on Windows Update and a previously unknown bug within their network resource allocation algorithm.

Too many people installed updates from Microsoft at the same time and then rebooted. That resulted in them all trying to sign back into Skype at the same time. It put a huge strain on the network and it couldn't handle it.

Yeah, I read that yesterday in Ars Technica, but it seems like a pretty stupid explanation to me, because the same time I saw that line I asked myself: "How about the other Patch Tuesdays?". They didn't give an explanation to that.

EDIT: Ok, the Skype guys revealed more things regarding the incident. It still makes less sense than before, oh well...

Here's what Microsoft had to say on Skype's outage...

Microsoft'a response to Skype's Outage

Well for the record all of my machines did the ms updates at the same time and rebooted themselves. I haven't ever seen all my machines run the same updates at the same time-ever. Which would make the ones with Skype log in at about the same time.

That ms article does not say if the updates happened all at the same time or not. That issue is not addressed. It only says it was administered like the rest of the updates. Which leaves out the deployment timing completely, avoiding any discussion of it's deployment software upgrades or patterns.

True Skype had a bug though and it was good that it was found. When I use Skype there is usually 5 to 6 million users actively online. That's quite a bit of logging on at the same time and the servers got it unexpectingly.

Overall it was a good experience for Skype to learn by. And not surprised at all by ms's reply in denying it's impact of rebooting millions of computers at the same time, since it automatically rebooted after the updates.
