It's 1434 and I also see 137 138 551. Big DDOS. It's hitting everything on our network coming from lots of different places...

Anyone seeing routing problems with Level3 at this hour? I just witnessed tons of prefixes behind level3's network withdraw. Any information on what is happening (if you know) would be great.
