In October 2015, a New York district court ruled in favor of the academic publisher Elsevier, which had accused Sci-Hub, a website that offers pirated versions of academic papers, of copyright violation. That decision allowed authorities to take down the site’s domain name, sci-hub.org. Suspending a domain name does not delete a website forever, though, it just prevents visitors from knowing where exactly to find it. It’s trivial enough to relaunch the same site under another domain, as Sci-Hub did.
