Update: An update from the Twitter status blog: “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.”

We’re still in shock over what has just transpired.Twitter was just hacked. A group claiming to be the “Iranian Cyber Army” took over TwitterTwitter and stuck its own text, logos, and images on the site.

Twitter’s security resume was badly damaged in July when hackers stole secret company documentsdepicting its operations. Yet even that didn’t take down the website. It’s also had its share of security exploits and fail whales.

Little compares to what has happened tonight. Even if it was a 3rd party DNS attack, Twitter still gets the black eye.

This is unacceptable for one of the world’s top 20 most visited websites. There needs to be accountability for this situation (no matter if it’s within Twitter or within a third paty), and a more detailed explanation is warranted. Twitter also needs to find a way to assure that this never happens again.

We’ve reached out to not only Twitter, but to the hackers themselves for comment.

Okay, we’re not entirely sure what Google is counting down to [ahem, New Year], but when you go to the Google homepage and click on the “I’m Feeling Lucky” button without typing a query, a countdown time appears with more than 1.7 million seconds remaining as of 3 PM Pacific Time. Apparently this is rumoured to be a countdown to the New Year.

However, what if it isn’t a countdown to the New Year but rather a Countdown to the release of the new Google Nexus One smartphone?

I’m not that good at mathematics to work out whether the amount of “seconds” works out at midnight December 31 2009, so really this is just speculation, but it could be a countdown to the Nexus One, and there’s nothing on the page that says it’s a countdown to anything else. 

 when the 1.7 million minutes are converted into days, the results are about 20 days. The only thing we can think of happening in 20 days is New Year.

So what do you think, countdown to New Year or to the arrival of the Nexus One, if you do the maths be sure to drop us a comment in out comment section below. and Let us know your theories of what Google is counting down to.

Many people says that It may be release of Wave or Nexus one or New year.. lets see what happens after count down 🙂
