Social media sites Twitter, Facebook, and Youtube and messaging service Whatsapp are currently being blocked across Turkey according to an incident report by Turkish Internet watchdog organization Turkey Blocks. Originally, Turkey was only blocking the original trifecta of social media sites: Twitter, Facebook, and Youtube.

Social media services blocked in Turkey amid ongoing political unrest

The social media block lines up with an operation currently ongoing by the Turkish government to arrest pro-Kurdish political party members from the HDP headquarters in Ankara. Arrested members thus far include the co-leaders of the HDP, Selahattin Demirtas and Figen Yuksekdag. The incident report reveals that the blocks started around 1:20 AM local time Friday morning. As with the previous shutdowns of social media services (it’s happened several times this year), the block is being enforced by the increasingly restrictive country’s few Internet service providers (ISPs). The throttling and bans start at the largest ISP, TTnet, which covers more urban areas, and hasn’t reached some smaller ISPs such as Uydunet, yet. Those that are able to access social media have been keeping the world updated on the unfolding events. There is even Periscope footage from the arrests at HDP headquarters in Ankara. This shutdown of certain parts of the Internet is technically legal in Turkey. President Erdogan is using a law that allows the President to use the Internet’s kill switch however he or she wants during an “emergency situation.”

Amid the ongoing “emergency situation,” there are reports that the Turkish army is moving towards the Iraqi border and also that additional warrants will be served on all HDP parliament members. The night is still ongoing and it is possible that Turkish ISPs will attempt to block or throttle traffic to other social media services, as well.
