Sri Lanka blocks social media during anti-government protests

April 4, 2022
Over the weekend, the government of Sri Lanka ordered ISPs to block Facebook and Twitter in response to anti-government protests .

According to Kentik aggregate NetFlow, traffic from Facebook (pictured) dropped away around 17:30 UTC (11pm local) and remained down for the next 15 hours. Consequently, there was also a surge of traffic from other content providers the following day as Sri Lankans used VPNs and alternative communication tools. This surge in traffic was also evident in the Radar Internet monitoring tool from Cloudflare.
