LIVIUS.ORG was reported hacked yesterday. I noticed it was down, and then Judith Weingarten linked to Roger Pearse's notice of the attack on FB. Everything seems to be back up today and I can find nothing about the attack on the Livius website itself.
Regarding Roger's post, I really don't think this episode justifies banning all Muslims, or even all of Turkey, from the Internet, and if we were to take that rather unfocused collective approach the Chinese and the Russians would be well ahead in the queue. A more productive course would be to track down and punish the actual perpetrators, whoever they are. I trust that this is the approach that the authorities are taking.
UPDATE: Jona Lendering has an account of what happened here. I have to say I'm a little jealous. But maybe Blogger just has better hacking countermeasures.
