The U.S. State Department doesn’t usually take an interest in the maintenance schedules of dotcom start-ups. But over the weekend, officials there reached out to Twitter and asked them to delay a network upgrade that was scheduled for Monday night. The reason? To protect the interests of Iranians using the service to protest the presidential election that took place on June 12. Twitter moved the upgrade to 2 p.m. P.T. Tuesday afternoon — or 1:30 a.m. Tehran time.
