Hopefuly they are claiming
'The Google Block was an Error'. What about the other ones which they do wrongly and the website never gets back? Some other countries have also blocked our access to their websites... I have faced this in many cases recently; The one which would remain will be 'iran.ir' one day...
"Iran has blocked access to the Google search engine and its Gmail email service as part of a clampdown on material deemed to be offensive. Hamid Shahriari, the secretary of Iran's National Council of Information did not explain why the sites were being blocked. Google, Gmail and several other foreign sites appeared to be inaccessible to Iranian users from Monday morning. Iran has tough censorship on cultural products and internet access, banning thousands of websites and blogs containing sexual and politically critical material as well as women's rights and social networking sites."
That didn't take long. Iran has now unblocked Google claiming the censorship was an error.
