Arista Records, LLC v. Tkach, No. 15-CV-3701 (AJN), 2015 BL 182234 (S.D.N.Y. June 03, 2015).
A third-party service provider is bound by and subject to the TRO and preliminary injunction in the Grooveshark case, finds Judge Nathan in the Southern District of New York.  The Court concluded that CloudFlare wasin active concert or participation
 with the Defendants based on the following facts: (1) CloudFlare 
admittedly owns and operates the authoritative domain name server for 
the new Grooveshark sites, which connects users entering the Grooveshark
 domain names into a web browser to the specific IP address associated 
with that  site; (2) CloudFlare provides other services designed to 
improve the performance of the new Grooveshark sites; and (3) CloudFlare
 began providing its services to grooveshark.li after
 it acknowledged receipt of the TRO.  Furthermore, for the purpose of 
determining whether CloudFlare is in active concert or participation 
with the Defendants, it is not determinative that CloudFlare's services 
are automated, that CloudFlare lacks a specific desire or motivation to 
help the Defendants violate the injunction, or that the Grooveshark 
sites would continue to exist even without CloudFlare's assistance. The 
Court thus hereby concludes and clarifies that CloudFlare was bound by 
the TRO and is now bound by the existing preliminary injunction.
