As the situation in Iran continues to play out, and as the people of Iran continue to use Twitter to plan their protests, Twitter has canceled their scheduled maintenance. According to the Twitter blog they stated that they realize their role in the protest going on in Iran and feel an obligation to stay online during these trying times.

In a blog post Twitter states that:

Down Time Rescheduled

A critical network upgrade must be performed to ensure continued operation of Twitter. In coordination with Twitter, our network host had planned this upgrade for tonight. However, our network partners at NTT America recognize the role Twitter is currently playing as an important communication tool in Iran. Tonight’s planned maintenance has been rescheduled to tomorrow between 2-3p PST (1:30a in Iran).

Our partners are taking a huge risk not just for Twitter but also the other services they support worldwide—we commend them for being flexible in what is essentially an inflexible situation. We chose NTT America Enterprise Hosting Services early last year specifically because of their impeccable history of reliability and global perspective. Today’s decision and actions continue to prove why NTT America is such a powerful partner for Twitter.

So it seems that the social networking site is taking on a new role in world affairs.
