So cyberwar is dead, is it?

You could be forgiven for thinking that, given the flurry of news stories saying to in the last week, but Al-Jazeera's english-language website was apparently hit by a Denial-Of-Service attack within hours of going live.

Now it looks like their arabic site has dropped off the net, too. It was there two days ago.

[edit: 48 hours later, the arabic site is back. The "English" URL serves the same Arabic page]

Seen: To Mars By A-Bomb
