Marshall-

AS 59 turned back up MSDP peering with AS 2381 ~ 12:10 CST.  We are
systematically blackholing infected hosts as we find them.

Is this causing problems for people (ie do we need to shut back down?)

What prefix are checking for Wisconsin connectivity?  I just checked the
Atlanta Abilene M5 for 128.104/16 and it's in the table.

MSDP SA's are spiking again, and Wisconsin seems to have dropped off of
the MBGP Internet.

Here is a little info
