Yep, soBGP or S-BGP could have prevented this. But that seems to be a bridge too far right now. I don't know about the cause - malicious or accidental - perhaps somebody from Level3 or Hanaro Telecom can explain the rest of the story. Marc -----Original Message----- From: Steven M.

I put up a diary at the Storm Center (http://isc.sans.org/diary.html?storyid=3112) that summarizes what we know about the Yahoo outage on Friday. If anybody has any additional info they want to share or comments about the write-up please let me know.
In other words, it was yet another BGP screw-up that secured routing could have prevented. Any clue about the root cause, i.e., malice or accident? --Steve Bellovin, http://www.cs.columbia.edu/~smb
