Good news for the U.S. is really bad news for Syria. And Libya. And ... Greenland.
What happened in Syria this week -- a wholesale disconnection from the Internet -- could happen anywhere. But it's more likely to happen in some countries than others.
The web services firm Renesys often analyzes that risk -- for, say, companies that are deciding which countries might make good hosts for data centers. And, in light of the Syria situation, it has conducted "a census, from our own view of the global Internet routing table, of all the domestic providers in each country who have direct connections (visible in routing) to foreign providers." Using that information, the firm created the chart above.
The illustration here is mostly unsurprising: Syria, Libya, Tunisia, Myanmar -- countries led by volatile and/or autocratic regimes -- are the most at-risk, while (relatively) stable democracies and commonwealths like the U.S., Canada, and European nations are relatively resistant to blackout.
