Two days ago, the Internet Services Unit (ISU) at King Abdul-Aziz City for Science and Technology (KACST), the governing body of the internet in Saudi Arabia, have blocked Blogger, denying users inside the country accessing their blogs. They have also blocked photos from the popular photo hosting service Flickr. Users still can log on to the site, but photos are no longer visible.
During the past two years, ISU have blocked the domain BlogSpot.com, where blogs that use Blogger are hosted for free, several times, but then unblocked it. The same thing happened with Flickr, too.
Update 1: Reporters Without Borders today called on the Internet Services Unit (ISU), the agency that manages Web filtering in Saudi Arabia, to explain why the weblog creation and hosting service blogger.com has been made inaccessible since 3 October, preventing Saudi bloggers from updating their blogs.
Update 2: According to Ibrahim Owais and Farah, Blogger.com is back in Business at Saudi Arabia. Ibrahim mentions that flickr.com, megaupload.com, livejournal.com and the list goes on, are still blocked.
