Reading the Skype blog post, it doesn't sound like the problem was due to lack of central resources, but rather some catastrophic bug in the P2P network itself -- like it was unable to reform the DHT (or whatever) in the wake of a massive churn event.
I mean, it shouldn't take *2 days* to log in 9 million users, and unless this was coupled with servers actually suffering hardware malfunction (of which there's no indication), I can't see any reason why it'd take that long to simply deal with a big backlog of authentication requests. Does anyone know much about the Skype P2P/DHT/network algorithm, and can they hypothesize what sort of event could cause it to take so long to get back into operation? Also, was Skype 100% down for 2 days followed by it coming 100% back up (indicative of a central server problem), or was it suffering from varying levels of failure throughout that took a couple days to clear up (suggesting P2P network problems)? -david > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:p2p-hackers- > [EMAIL PROTECTED] On Behalf Of Alen Peacock > Sent: Monday, August 20, 2007 1:39 PM > To: theory and practice of decentralized computer networks > Subject: Re: [p2p-hackers] what really happened to Skype? > > Absolutely true that Skype hasn't given us enough details to figure > out exactly what happened or why, but that doesn't prevent the looser > cannons among us from taking a shot: > http://flud.org/blog/2007/08/20/p2ps-skype-induced-blackeye-or-why- > diversity-is-good/ > > Alen > > > On 8/20/07, zooko <[EMAIL PROTECTED]> wrote: > > Folks: > > > > This is a fascinating case study, but we don't yet have enough > > information to really learn from it! > > > > http://heartbeat.skype.com/2007/08/what_happened_on_august_16.html > _______________________________________________ > p2p-hackers mailing list > [email protected] > http://lists.zooko.com/mailman/listinfo/p2p-hackers _______________________________________________ p2p-hackers mailing list [email protected] http://lists.zooko.com/mailman/listinfo/p2p-hackers
