Authorities raided Nginx's Moscow office based on a copyright infingement claim by Russian oligarch Alexander Mamut’s Cyprus-registered investment vehicle Lynwood, Forbes Russia cited an unnamed source at the web server as saying. Mamut became part owner of Russia’s 1990s-era search giant Rambler with fellow oligarch Vladimir Potanin in 2013 and bought out Potanin’s stake three years later.
