Out of curiosity - does anyone know why Google is truncating ICMP responses ?
Assuming (not confirmed) mitigating old-style DOS attacks. See "ping of death." ICMP packets should be small enough to never require fragmentation. But large enough to contain at least the header of the original packet. When I used to write firewall stuff, there was a great debate about how much data to return in an ICMP error/reply packet. I don't think the debate was ever resolved.
