San Francisco-based Twitter rescheduled a planned network upgrade on Tuesday night (Pacific time) due to heavy activity from Twitter users in Iran.
In conjunction with NTT America, its network provider, Twitter carried out the planned maintenance on Wednesday afternoon (Pacific time) in order to keep services active during critical hours in Tehran. Twitter confirmed that it consulted with the State Department, but said the State Department does not have access to its decision making process.
