You can always ask.

The real question is what will the response be?  ;-)

This entire exercise is a race condition, just like checking for that a
file exists before deleting it, or that it doesn't exist before creating
it.

If you "have internet" when you check, what assurance do you have that
you will still "have internet" when you actually want to use it?

And if you don't "have internet" when you check, when do you check
again?

I think someone said it way upthread:  don't check, just do whatever you
came to do, and it will work or it will fail (presumably, your program
can tell the difference, regardless of a past snapshot of being able to
retrieve data from an arbitrary URL).

EAFP, anyone?
