Back to a previous thread about this, "down" is relative to 
the importance of the resource. If something was affecting
the Internet "globally", then you would need a more
holistic indicator.  

I wonder if watching routing tables for route withdrawals or
entire ASN's disappearing would be a useful way to do that. 
There are problems with aggregation and null routes, but 
it's a start. 

If they were able to get route views from multiple sites, 
it would be even more useful.
