I received an email today from Doug Madory of Renesys, a company that monitors the dynamic state of the global Internet.

Renesys is "The Internet Intelligence Authority" -- they constantly monitor the state of the global Internet. You may have seen their reports of network outages when nations went off line during the Arab Spring, for example, this Syrian episode. You can get a sense of what they do by following their blog and Internet events bulletin.
