Log-in/authentication is centralized in Skype, although distributed (http://en.wikipedia.org/wiki/Skype_Protocol). The Skype post says that the restarts "caused a flood of log-in requests, which, combined with the lack of peer-to-peer network resources, prompted a chain reaction that had a critical impact." That remains very nebulous, at least to me. But it seems clear that the author was highlighting the failure of the log-in system as causing cascading failures. This would make sense, if, for example, peers don't talk to one another unless they are already authenticated to the central servers. I have no idea if that is true or not, but something of that nature could clearly cause the chain reaction described.
