I noticed that some sites don't allow ping at all, some allow 1/4 to 3/4 and some allow all four pings across the board. Microsoft doesn't allow any pings, and BBC allows the full set.....
Also interesting how some sites have a very short TTL on DNS records, others very long, meaning that the former can change IP address and be up and running in very short time, and others, usually free hosts, may take up to a day to reset DNS.
