August 2008 — Russian military forces move into Georgia, citing requests for help from ethnic Russian communities in Georgian breakaway regions of South Ossetia and elsewhere. At the same time, DDOS attacks orchestrated out of Russia blocked access to Georgian government web sites. I don't know everyone's feeling on this, but if armored vehicles are rolling down the street in front of my home, and I see combat aircraft overhead and hear incoming artillery rounds, my inability to look at the Georgian equivalent of whitehouse.gov is going to be of relatively little concern...
This seemed to be another case of "Russian patriotic citizens rise up" and do the attack on their own, where the government does not direct them but neither does it stop them or even disapprove. Wired.com described how a Russian coder took credit for hacking Georgian sites including www.parliament.ge, the Georgian parliament's site.

October-November 2008 — Major news organizations started seriously questioning the accepted view of the military action is nothing but Russian aggression and Georgian self-defense, as Georgian targeting of civilians and other details come to light. See these reports:

September 2009 — Aviation Week and Space Technology ran an article (14 Sep 14 2009 pp 54-55) titled: "Cyberwar is Official" and subtitled: "Network attack, digital time bombs and information exploitation are now combat standards", quoting an analysis from the U.S. Cyber Consequences Unit (US-CCU), "only parts of which are available to the public". The article describes US-CCU as "an independent organization that does cyber-forensics and analysis for private organizations and government, including the National Security Agency and CIA."
