Well ...

Breaking the DNS resolution at (for example) iiNet doesn't break "The 
Internet". It just breaks users depending on that service.

Likewise, a local addressing issue - say a conflict in the home LAN - 
doesn't break "The Internet", it just *looks* to the user as if it has.

"The Internet can't be broken" is an oversimplification that doesn't 
tell you whether a tail is breakable, or a particular ISP, or a 
submarine cable, or (etc).
