The prediciate assumption that "pinging one destination is a valid check that my internet works' is INCORRECT. There is no magical unicorn that could be built that could make that true, and 'they're gonna do it anyways' is a poor excuse to even consider it. 


The predicate assumption that unsuccessful pinging one destination is a valid check that my internet DOES NOT work' is  ALSO INCORRECT. Still no magical unicorn. 

I am disappointed but not surprised to see this discussion on NANOG. Encouraging Users to use a tool (that is often ignored by the hardware targeted) by providing a non-revenue-creating special target does not make business sense.

An allied issue is educating ‘Users’ about traceroute AKA sequential ping with TTL progression:


I’ve lost count of my replies on user forums explaining this issue, even to otherwise well educated users. 

To be blunt, browsing to amazon.com, apple.com or another vendor site is a simple and easy to teach Internet aliveness check and, at least, offers the chance for the targeted vendor site to receive revenue from sales. I have no crisis of conscience from clicking an vendor shortcut for a basic end-to-end Internet functional test. Or for teaching a User to do the same. This meets the business purpose locally and requires no $pecial effort from Users, network providers, or target systems. This precludes memorization of IP addresses by end Users thus reducing the offered load from the likes of excessive ping 8.8.8.8. 

I would expect NANOG members to have favorite ping target addresses based on their environment, e.g., default router and a few designated targets. These are useful for manual debugging but, as mentioned previously, are not suitable as singular input to network monitoring.
