I ran it and got:

[Mon Oct 12]~ $ ping -s 1472 -M dont -c 4 security.debian.org
PING security.debian.org (128.61.240.73) 1472(1500) bytes of data.

Looks OK to me.  I changed the backports repo from debian.net to 
uchicago.edu and everything just flows.  Now, if I can only find the 
problem with security.debian.net, which as I understand it, has no 
trustworthy mirrors
