Whats the infatuation of ISPs with ping? I mean wasn't the ICMP designed for debugging networks? :/
Way back in spring 2001, Yahoo! was unreachable for about 24+ hours due to a massive Distributed DoS ping attack. Yahoo! put in the effort to block only the illegit requests but many sites decided to drop ICMP echo requests (e.g. www.redhat.com, www.att.com).
