The Obama administration says it has tried to avoid words or deeds that could be portrayed as American meddling in Iran’s presidential election and its tumultuous aftermath.
Yet on Monday afternoon, a 27-year-old State Department official, Jared Cohen, e-mailed the social-networking site Twitter with an unusual request: delay scheduled maintenance of its global network, which would have cut off service while Iranians were using Twitter to swap information and inform the outside world about the mushrooming protests around Tehran.
The request, made to a Twitter co-founder, Jack Dorsey, is yet another new-media milestone: the recognition by the United States government that an Internet blogging service that did not exist four years ago has the potential to change history in an ancient Islamic country.
“This was just a call to say: ‘It appears Twitter is playing an important role at a crucial time in Iran. Could you keep it going?’ ” said P.J. Crowley, the assistant secretary of state for public affairs.
Twitter complied with the request, saying in a blog post on Monday that it put off the upgrade until late Tuesday afternoon — 1:30 a.m. Wednesday in Tehran — because its partners recognized “the role Twitter is currently playing as an important communication tool in Iran.” The network was working normally again by Tuesday evening.
The State Department said its request did not amount to meddling. Mr. Cohen, they noted, did not contact Twitter until three days after the vote was held and well after the protests had begun.
“This is completely consistent with our national policy,” Mr. Crowley said. “We are proponents of freedom of expression. Information should be used as a way to promote freedom of expression.”
The episode demonstrates the extent to which the administration views social networking as a new arrow in its diplomatic quiver. Secretary of State Hillary Rodham Clinton talks regularly about the power of e-diplomacy, particularly in places where the mass media are repressed.
Mr. Cohen, a Stanford University graduate who is the youngest member of the State Department’s policy planning staff, has been working with Twitter, YouTube, Facebook and other services to harness their reach for diplomatic initiatives in Iraq and elsewhere.
Last month, he organized a visit to Baghdad by Mr. Dorsey and other executives from Silicon Valley and New York’s equivalent, Silicon Alley. They met with Iraq’s deputy prime minister to discuss how to rebuild the country’s information network and to sell the virtues of Twitter.
Referring to Mir Hussein Moussavi, the main Iranian opposition candidate, Mr. Crowley said, “We watched closely how Moussavi has used Facebook to keep his supporters informed of his activities.”
Tehran has been buzzing with tweets, the posts of Twitter subscribers, sharing news on rallies, police crackdowns on protesters, and analysis of how the White House is responding to the drama.
With the authorities blocking text-messaging on cellphones, Twitter has become a handy alternative for information-hungry Iranians. While Iran has also tried to block Twitter posts, Iranians are skilled at using proxy sites or other methods to circumvent the official barriers.
It is a new political day indeed.
