Dropping ICMP traffic isn't super uncommon to try to mitigate low-complexity DoS attacks, I also cannot ping irs.gov.

I can get to www.irs.gov in my browser though.

It's also a great way to introduce hard to debug network issues since PMTUD also relies on ICMP, and is basically mandatory for ipv6.
