Twitter, Facebook, down more power to Georgia?

Interestingly Google, Facebook, Twitter got involved in a denial of service, which brought these sites a bit of grief.
The reason attacks interested me was because twitterfeed.com which I use has been put out of action.

Interestingly as reported the attacks where related to the the Russian Georgian conflict. The person 'Cyxymu' was the intended victim for the attack. He/she used google, facebook, and twitter services.
It made me wonder was it the government of Russia that was behind these attacks; and if so it appears that its backfired on them. 'Cyxymu' now has more publicity internationally than he ever had. It also made me wonder if there was a war between two superpower. What would the cyber implications be....
