Iran has blocked external HTTPS websites

Few weeks ago, Iran moved most of its government websites to local servers in order to be safer to cyber attacks. Now, they have blocked access to external websites that use HTTPS protocol. For example citizens couldn’t access Hotmail, Gmail, Facebook, Yahoo! Mail and websites of Banks that use HTTPS. On the other hand citizens can access websites that use HTTPS but are hosted in Iran. We currently don’t know the reason and some believe that is linked to the anniversary of the 1979 Islamic Revolution in Iran. Others believe that it has to do with the Iran’s nation-wide state-sponsored Intranet that would be up and running soon. It was announced by Republic News Agency and this might be a leverage to force its citizens to use it. Iran is taking censorship to the next level.
