All emails I’ve sent to folks in Iran over the past couple of days are being returned by the Mailer-Daemon. I then googled news and found out that Gmail indeed has been blocked in Iran over the past 24 hours. But usually when the blocking has happened in the past nothing happens and you get no Mailer-Daemon message either. It seems the regime is really going out of its way this time!
I am still getting Facebook messages and Tweats from folks over there, though. Has anyone experienced any interruptions on these services yet?
