It seems Twitter has got into the festive season a little too early, and has gone down just minutes ago.

According to Down For Everyone Or Just Me Twitter is well and truly down at the moment – with pages “failing to open”. Even Twitter’s status page has gone offline, as well as the company’s business Twitter 101 subdomain.
Ever since first launching, Twitter has always had scalability issues – leading to downtime frequently. Recently however, on the back of more funding and more employees the service has managed to scale up and remain up more often than it is down.
UPDATE: TechCrunch is reporting the site was attacked by a group claiming to be the “Iranian Cyber Army” who defaced the site and left this message:
THIS SITE HAS BEEN HACKED BY IRANIAN CYBER ARMY
iRANiAN.CYBER.ARMY@GMAIL.COM
U.S.A. Think They Controlling And Managing Internet By Their Access, But THey Don’t, We Control And Manage Internet By Our Power, So Do Not Try To Stimulation Iranian Peoples To….
NOW WHICH COUNTRY IN EMBARGO LIST? IRAN? USA?
WE PUSH THEM IN EMBARGO LIST
Take Care.
UPDATE 2: Given the seemingly large scale of this attack it’s a best bet to change passwords on your major accounts if they are the same as your Twitter account. It seems this is one huge security compromise and its best to be on the safe side.
UPDATE 3: The web is lighting up with reports on what’s going on. No one seems to know who this group is yet, and Twitter hasn’t yet come back up. Strangely enough some API calls still seem to be getting through, and Twitter Search is still working.
UPDATE 4: And we’re back it seems. Twitter.com is working again. No word yet on what damage (if any) was done. Twitter’s status site is still down though. It seems the other subdomains are slowly coming back online – the API is now working again. Twitter’s help site still seems to be down, although this is more likely a caching issue rather than anything else.
UPDATE 5: Twitter’s Status site is now back online – here’s the official word so far:
We are working to recovery from an unplanned downtime and will update more as we learn the cause of this outage.
UPDATE 6: And there’s no need to panic now or change your passwords. Twitter has confirmed the DNS records were “temporarily compromised” which means user data wasn’t touched and the “hackers” simply redirected users to their own website. Full tweet below:
Update (11:28p): Twitter’s DNS records were temporarily compromised but have now been fixed. We are looking into the underlying cause and will update with more information soon.

Why should we change our passwords? Wouldn’t Twitter be storing them hashed? If Twitter have set things up correctly then there should be no way for anyone — Twitter themselves, a data thief, or anyone else — to recover any passwords. If Twitter are storing passwords in cleartext or any other recoverable form then it’s time to run a mile away from the service anyway, I’d have thought.

Sorry @Draven – as it turns out it was a DNS redirection and as such user data wasn’t affected.

@Paul point taken. At the time we weren’t sure how deep the attack had gone, and we were just advising in case the attackers had managed to gain access to all data.

The attack doesn’t seem to have breached anything but the way the twitter.com domain was being resolved by DNS servers. I guess we’ll have to wait for Biz to tell us more.
A bit more color on the whole situation:

Somebody please correct me if I’m wrong, but isn’t the issue with the passwords related to third-party apps?
For instance, TweetDeck has my password. If the attackers pointed Twitter’s DNS records elsewhere, and if TweetDeck tried to log on to twitter during the attack, wouldn’t TweetDeck have sent my credentials to the attackers’ servers?
That seems like a bad thing. If that’s not actually a concern, somebody please clue me in!

This is the first time I have come across i.techreport. Your coverage of today’s Twitter attack is very impressive. First class journalism. I’ve become an instant fan.
Congratulations and thank you.
