Yup. And Google folks accounted for the world pinging them all day long.
I wouldn't call using DNS resolvers as best "am I connected to internet over this interface" tool though. A day, year or 5 years from now the same team may decide to drop/filter and then thousands of hardcoded "handmade automation solutions" will break. And I believe that's closer to what Masataka was trying to convey.
I get that, but what I'm saying is that users tend to expect things to remain the same. In reality, they don't, because as abstract as the Internet seems to most users, it is run by actual people, who have to apply mind and muscle to not only stand things up, but keep them standing. The movement of those people has an impact on that, even in very well established institutions. So unless there is some specific accommodation from Google et al, that the servers they run for one service can be used for liveliness detection, expect breakage when that changes, at their whim. Until then, do not expect users to honour the original intent of the service. If it can serve some other purpose (like liveliness detection), they will use it for that purpose in the hopes that it will always be there, for that purpose. Mark.
