Turkey has blocked access to social media following an attack on Turkish troops in Idlib, Syria on Thursday 27 February 2020.
Social platforms Twitter, Facebook and Instagram became unreachable at 11:30 p.m. local time (8:30 p.m. UTC) via national provider Turk Telecom (AS9121) and subsequently other leading service providers. Data show that YouTube and WhatsApp messaging backend servers were also partially restricted at the same time or shortly after. The restrictions are technically consistent with techniques used to filter content in Turkey, with SNI and DNS filters in use varying by provider.
