So it's too late.  Don't bother upgrading now; you're already owned.
Unless they are blocking it at the ISP borders in the same way they
blocked out the Cisco IPv4 Crafted DoS vulnerability in 2003.  ISP's
probably got the patch (or at least Cisco's ISP's did) a week ago.
Had rolling reboots lately?  Don't know why?  Lots of "miscellaneous"
ISP maintenace.  I wonder...



Ahhhhhhhhhhhh....

So many routers, so little time...
