Oh yawn, Eric..
When are you going to make a remark that is actually a bit hard to counter?
1) Here are some independent stories about it (stating the obvious, since it took a 1 sec. search)
The latter two (ZD Net and The Register) are leading IT news sites in case you did not know. That is apart from the fact that they mentioned it on the RT News.
2) The site was down for about 24 hours, I just happened to make my post at the end this period.
The group taking responsibility was called "anti leaks" - same group which ddosed wikileaks itself at the time of the big cable leak. Apparently they object to RTs coverage of the Assange affair.
