I believe this to be an automated event. If you compare which supernodes went down to those that didn't the version numbers are similar. I've captured these packets and decrypted them and currently looking into my findings. Most of the supernodes were non-responsive at ~12:00 EST. There were only ~2k routing traffic at the peak of this event and the network requires ~71,000 to support peak load hours. It will be interesting to hear what they claim happened. > There are some other guesses which I hope to share later :) > > Salman > _______________________________________________ > p2p-hackers mailing list > p2p-hackers@lists.zooko.com > http://lists.zooko.com/mailman/listinfo/p2p-hackers _______________________________________________ p2p-hackers mailing list p2p-hackers@lists.zooko.com http://lists.zooko.com/mailman/listinfo/p2p-hackers
