Not really. It can ping whatever resource it needs "the internet" for in the first place. After all, if that's down, then no amount of "internet" connectivity will help.

I put "internet" in quotes because it's not really a well-formed concept. How much of the global network needs to be accessible to count as "internet access"? Your home LAN? Your country? A specific server in Larry Page's basement?

When it's connecting to a wifi access point your phone or device doesn't know what resource you'll actually request so instead it pings the most resilient thing a Google engineer could think of at the time without risking DDoSing someone which is Google.

We are talking about smart home things here though, which usually depend on their own services anyway.

This is more of a problem with things like Windows reaching out to msftconnecttest.com or some other generic internet service. But in the case of a smart home device it's needs are usually more well defined.

This becomes harder with a consumer router trying to determine if it is online though unfortunately because of exactly what you describe.

If you're trying to figure out if a failure is from the service you're trying to hit, or if it's the connection of the current device, you need to hit a separate, third resource. To be resilient/fast enough, for most product you'd probably hit a static file on a well known CDN. If you work at google, google.com is honestly not a bad idea.

If you just try to ping the resource you were going to access, for all you know it's the resource that's down.
