I got to thinking... I assumed Mercy to mean she received an ICMP
type 11 + code 0. If it's code 1, that's a "fragment reassembly
time exceeded"... which I _think_ can be generated by a host, but
don't quote me on that.
Perhaps somebody was scanning www.microsoft.com using packet
fragments, and a big mess of source addresses in an attempt to
obfuscate their own IP. i.e., maybe Mercy is seeing backscatter
from someone trying to scan MS.
