You mean like PMTUd, and such :-)? We probably won't get that one back, and unless we do something, inability to ping 8.8.8.8 will result in unnecessary NOC tickets claiming "the Internet is down".
That's /one/ option.
Another option is for Google, et al., to simply drop ICMP packets to their DNS servers.
Is this heavy handed? Probably.
Is it a viable option to persuade people to not ping said DNS servers? yes.
Will it achieve the desired result of having people stop pinging Google's DNS servers? Quite likely. Admittedly with a long tail.
Yes, this helps Google not having to deal with the problem, but it passes the burden both to the ISP who has to explain why the Internet is now down, and to some other online service who now has to sink ping traffic. Perhaps Yahoo will pick that priviledge up again, like they did back in the day :-(... Mark.
