Watching North Korea's Internet Connectivity Go Up and Down Via Twitter

One thing I enjoy about following Dyn Research (formerly Renesys) on Twitter is that they provide quite interesting graphics and charts about Internet outages. They've been tracking North Korea's Internet access quite closely over the past week and their tweets have been quite enlightening.

Back on December 22, for instance, DynResearch tweeted a chart showing a 9-hour, 31-minute outage:

The next day, December 23, they showed North Korea's Internet access being unstable:


Then today, December 27, DynResearch has been tracking another outage that was greater than 5 hours:


Akamai's "State of the Internet" Twitter account also tweeted out a chart showing traffic to North Korea dropping to zero today:


Thanks to both DynResearch and Akamai for providing these charts about this Internet outage and so many others. It's great to see real measurements and data — and to see those measurements visualized — to understand more about the Internet's infrastructure in different parts of the world. And if you aren't following those accounts on Twitter, you may find them quite useful to do so.

Hello, at CAIDA ( @caidaorg ) we twitted about our live graph (30min delay) where people can follow North Korea's connectivity hiccups online. The graph is also interactive. For example, you can zoom in to see the last few hours with better detail.
