Internet censorship has dramatically increased in Iran over the last week. On 7 February, internet users in Iran began reporting an increase in the blocking and filtering of certain kinds of internet traffic in the country. Many users complained of not being able to access HTTPS websites, the secure and encrypted version of HTTP protocol. Many banks, Google services, Twitter, Facebook, and Microsoft Hotmail use HTTPS to protect private data. Though there have been no official announcements regarding the changes, it is widely believed to be the first step towards a Halal internet.
