A Radio Farda staffer emails:
While reports from Iran indicate that all foreign sat TV signals have been jammed, Radio Farda and especially its website remain one of the few open channels for the people in Iran.
Our filter-busting software was launched just in time. Yesterday and today we have had 90,000 visits from Iran - more than twice the election campaign period daily average, which was a peak in itself. We have had 4,300,000 hits in two days, which is one quarter of all hits in the month of May. The day is not over yet and only today we might reach 75,000 visits.
However, it is possible that they will shut down internet completely. There are reports from Iran that now even local phone service is being shut down.
