You'd never know - one cable (or was it two?) brought down just about the entire middle east and many other areas...
Seems like accessing many sites is very slow today - this site doesn't seem to be too affected by it but gMail is horrible, Facebook is slow, and a couple of other forums I visit are very slow.
Edit: I'm starting to think Google is the culprit. I did a search and the image hadn't even loaded up before I was done typing and took about 10 seconds to pull up the results. If they're slow, it could ripple out to tens of thousands of sites.
