Turkey has taken their censorship of Twitter to the next level.
Initial blocking was done through DNS, so it could be easily bypassed by using something like Google DNS at 188.8.131.52.
Turkey quickly responded to the masses of people using that workaround, and are now blocking Twitter by IP address.
As one often sees with attempts at censorship, this one was counter productive. It looks like tweets from Turkey actually increased 138% following the DNS block.
Now that the censorship is IP based, a VPN like Anonymizer Universal will be required to continue to access Twitter and any other services that may be blocked.
We continue to test that service from within Turkey, and it looks to be working well.
