Washington: Al Qaeda's main Internet sites have gone silent for more than a week in an unprecedented outage for the extremist network's online forums, analysts said Tuesday.
"All of them essentially went down" as of March 23, said Aaron Zelin, a researcher at the politics department at Brandeis University.
The outage hit a number of online forums including two "flagship" sites, al-Fida and Shamukh al-Islam, which serve as a channel for Al Qaeda forums, providing a stamp of approval for any associated sites, Zelin said.
"The forums authenticate Al Qaeda's message, therefore they're very important," said Zelin, who writes about extremist Islamist sites on jihadology.net.
"If someone is a true believer in the cause, they're going to go to the forum because they know it's the only place they can get Al Qaeda's message."
One of the two main sites, Shamukh al-Islam, reappeared online on Monday but had not yet resumed message threads, he said.
A "second-tier" site, Ansar al-Mujahideen Arabic Forum, was restored within three days, he said.
No one has claimed credit for the blackout, which bore all the signs of a cyber attack, analysts said, as the forums usually post messages announcing a temporary interruption if they close the sites themselves.
The digital sabotage could have been carried out by any number of governments or private hackers, said James Lewis, director of the technology and public policy program at the Center for Strategic and International Studies.
"There are some many potential suspects," Lewis told AFP.
The long silence from the sites suggested Al Qaeda was having difficulty getting service restored and was no longer as capable in the cyber realm.
"It's not a good sign for them that they can't straighten this out more quickly," Lewis said. "It could be seen as sign of decline."
The last time Al Qaeda's sites faced a major outage was in June 2010, when British intelligence sought to block the release of an online magazine from Al Qaeda's branch in Yemen, according to Zelin.
Western officials have often debated the best approach to Al Qaeda's online presence.
Although the group's forums are used to encourage terror attacks and spread extremism, the sites also provide a way for intelligence services to monitor the network's militants.
"There is always a debate over whether it's better to exploit or to disrupt. In this case, since one site came back up, it might be a way to funnel jihadis and make them easier to observe," Lewis said.
