In the past ICMP pings to netlify domains worked, but they seem to have recently stopped.
For example, www.chrisbentzel.com DNS configuration shows it is a CNAME for brave-mahavira-e1bab3.netlify.app
;; ANSWER SECTION:
www.chrisbentzel.com. 3440 IN CNAME brave-mahavira-e1bab3.netlify.app.
brave-mahavira-e1bab3.netlify.app. 20 IN A 126.96.36.199
brave-mahavira-e1bab3.netlify.app. 20 IN A 188.8.131.52
pinging the domain name or the IP addresses directly shows no ICMP traffic going through. I am seeing ICMP traffic succeed on other addresses so do not think this is a local firewall issue or similar.
I am also seeing this behavior on other netlify hosted pages on different domains.
I looked at the new firewall traffic rules and they have “Allow all traffic” set.
