Facebook: Israel / Syria
I spent a chunk of January in Syria. Whenever I dropped into an internet cafe the instant offer was "You want FB?" to which I generally replied: "OK, sure". Attendant swapped HOSTS file to a Western friendly version and Voila! FB works.
I'm supposed to provide passport and have all surf details recorded. Syrian gov hasn't [yet] got a clue about national firewalls. FB is banned as allegedly it is a device used to spy on Syrians.
PS As an aside: I've travelled extremely extensively and have yet to meet a more hospitable people than the Syrians I encountered.
Biting the hand that feeds IT
