The official Skype post-mortem of the outage was posted yesterday. It's an interesting read because there is more detail than you usually get from large companies, who generally prefer not to air their laundry in public. Here is some commentary on the report. The US$1 credit was a nice gesture, too.
I wish events such as these would encourage people to seek alternatives to Skype, but there are two reasons why that won't happen. First, Skype is deeply entrenched and it will take much more than a 24 hour outage to rip Skype from everyone's psyche. Skype would have to be totally non-functional before my family would switch. Second, most of the alternatives suck in the client department. Find me a usable SIP client for Linux, please. Anyone? Didn't think so.
As much as I dislike the proprietary nature of Skype, it's one of those deals with the devil I've learned to accept. I'm going to hell anyway, so what difference does it make? ^_^
