checking internet connectivity

[Moritz Both]

Please excuse me if this is a frequently discussed question; i have 
searched but found it difficult to find good search terms:

How do folks check Internet connectivity?

Checking the "presence" of "the Internet" is neccessary to us to make 
other checked hosts and services dependent on that, i.e. we dont want to 
generate notifications for services we check but which are located 
somewhere else when our own Internet connection is gone.

- Do you simply ping www.google.com or something?

- Is pinging third party hosts considered unfriendly since we use their 
bandwidth? (Do you ping hosts you dislike for this reason? :)

- Is there a best practice for that?

- Even Google can vanish, but in that case we still would like to check 
our services.

Thanks for any hints,
Moritz
