Unable to ping US websites

For some months now it seems that US ISPs have changed their routers and drop ICMP packets to many websites/hosted accounts across the pond.  You can try your own, but this is a typical result:
ping -c 2 www.networksolutions.com
PING www.networksolutions.com (205.178.187.13) 56(84) bytes of data.

Have you noticed the same?  Do you know why this is so?
The above makes ping tests impossible and breaks typical connectivity tests run by various applications (e.g. Nagios).
