And others are trying it in the field now.  I setup the recommended
transit ACLs yesterday.  Starting at 9:25am EDT this morning, those ACLs
started getting hits.  What doesn't make sense to me is according to the 
advisory, the packets have to be destined for the router to crash it (not 
just passed through it), but people are attacking seemingly random IPs, 
including ones in a new ARIN block that have not yet been assigned/used 
for anything.  What do they think they're attacking?
