The Iranian government announced on Sunday that Gmail and Google would be filtered nationwide until further notice, and it also sent out the notice as a text message to citizens' mobile phones. Google Search is accessible but isn't functioning properly, Google services which need a secure SSL connection can't be accessed, and Gmail is out of reach. There's speculation that the moves are a response to an anti-Muslim movie that has sparked riots throughout the Muslim world and been banned from YouTube, but some contend the "filtering" of Google services is a prelude to a nationwide firewall Tehran plans to implement.
