It is interesting to note that Yahoo! presented @ NANOG a couple days ago
they were getting XX Mbps (15? I forget) of ICMP traffic. They mentioned
they could use this data in a decision whether to considering limiting ICMP
(without actually saying they were considering limiting ICMP).
Yahoo! has been relatively good to the Internet community, and making them
pay for random tests seems to be a bit less than polite, IMHO.
Perhaps we should pick something else to ping, something that is relatively
ubiquitous, something that everyone knows, something that should be up all
the time, something that has good connectivity, something that everyone
here would not mind sending random packets for random reasons ....
Yes, I think we all came to the same conclusion. From now on, everyone
should ping www.microsoft.com to test connectivity. :)

Personally, I would ping my upstream and/or some other location on the 'Net
if XXX did not respond before I did "sho run". But that's me. :)
