I just tried to take a look at my Flickr page and found the following message in its place: "We apologize the site you are attempting to visit has been blocked due to its content being inconsistent with the religious, cultural, political and moral values of the United Arab Emirates." I don't know if this is the case for the whole country, or just from where I am (the press center at the Arabian Travel Market). I recall there being tons of photos from Dubai on Flickr. UPDATE: Apparently it's blocked outside Dubai Media City, which is where my office is.
