Cyber-attacks against anti-racism organisations shot up in the wake of the death of George Floyd, a leading provider of protection services says.
Cloudflare, which blocks attacks designed to knock websites offline, says advocacy groups in general saw attacks increase 1,120-fold.
Government and military websites also saw a notable increase in attacks.
Cloudflare says that after Mr Floyd's death and the ensuing violent clashes between police and protesters, it saw a noticeable jump in the amount of requests it blocked - an extra 19 billion (17%) from the corresponding weekend the previous month.
One single website belonging to an unnamed advocacy group dealt with 20,000 requests a second.
Anti-racism groups which belong to Cloudflare's free programme for at-risk organisations saw a large surge in the past week, from near-zero to more than 120 million blocked requests.
