This morning, a lot of things were explained.

Maybe these hackers were partially responsible for yesterday’s intermittent service. Maybe the odd behavior from Twitter was merely a precursor for what PCWorld reported early this morning. Maybe I was the only one thinking about the DoS Attack from this summer, but Twitter was once again under fire. A group referring to themselves as The Iranian Cyber Army redirected for a brief time all Twitter traffic to a landing page of their design. Sumner Lemon of IDG News Service reports:

Visitors instead saw a black screen with an image of a green flag and Arabic writing. The defaced site also included a message that said, “This site has been hacked by Iranian Cyber Army,” and an e-mail address.

Twitter blamed the outage on changes made to the company’s DNS (Domain Name System) records, which match the company’s domain name with the IP addresses of its servers.

Meanwhile, the news from Twitter Status was that as of 11:28pm, last night:

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.

So far, nothing new has really surfaced apart from critics who are saying this is just another show of how vulnerable Social Media sites are. I, for one, applaud Twitter’s resilience. They only lost service for an hour (which was probably when I was engrossed in my weekly dose of Mythbusters…) and managed to bounce back. Yesterday had been a somewhat uneven day for Twitter, but they have seen worse. Much worse. I think yesterday’s performance is proof extremely positive that Twitter has learned their lessons from previous growing pains.

So as the dust settles from yesterday, just remember…

…and tweet happy!
