Skype is now blaming Microsoft’s “Patch Tuesday” for the outage which disrupted their service for over 48 hours starting from August 16th. Skype believes that the massive outage was cause “by a massive restart of our (Skype) users’ computers across the globe within a very short timeframe as they re-booted after receiving a routine set of patches through Windows Update.”
It’s pretty surprising because Windows Update has been running since a long time and this isn’t the only instance of where users had to restart their computers after receiving updates. If massive restart was the reason for the outage, why didn’t this happen earlier?
Second notable point is that Windows Update by default restarts your computer after receiving updates at 3 AM. There is no way all computers can restart around the globe at once, unless everybody volunteered to set the same time to restart.
This move of blaming Microsoft didn’t do any good, except for fetching them some bad PR.

I somewhat doubt this. Most users don’t even have automatic updates enabled I’d guess (or at least not automatic restart). Plus, they’d have to have Skype set to start on bootup. At least on Linux this is not default.

This is just playing blame game. Microsoft periodically release update and it may happen that many time it needs more than a handful of users to restart their computer at the same time. So it is skype’s responsibility to make the necessary arrangement and make their network bug free.

Despite this headline that’s been floating around the blogosphere thanks to Slashdot, Skype never actually blamed Microsoft for the outage. If you look at the announcement they made (which you even linked to and quoted from), they took full responsibility for the problem in their login system.
They acknowledged that the problem was in _their_ system: the update “triggered” the problem, leading to “issue has now been identified explicitly within Skype.” There was a big update (bigger than the usual), and the higher-than-average logins triggered a problem with the Skype code, as explained in their announcement.
Skype never blamed Microsoft.

How is this even possible? I guess I don’t fully understand how the Skype network works, because a bunch of computers restarting shouldn’t have anything to do with being able to make an Internet phone call - at least in a perfect world.

I don’t agree microsoft is the reason for their “Patch Tuesday”. And it is very unlikely and next to impossible that all skype users restart their computers across the globe at one time

Blaming can’t bring trust, which a company lose by such type of incidence.
