We have confirmed that the Grooveshark Page and App outage on Facebook was due to a copyright takedown request issued by a foreign entity. As a fellow US-based DMCA-compliant service, Facebook’s copyright notice and takedown process is very similar to Grooveshark’s. We are working with Facebook to reactivate the Grooveshark Page and App in accordance with their process. In fact, this incident has created an even stronger line of communication and cooperation between our two companies. In the meantime, because Grooveshark has never forced users to login using Facebook, all Grooveshark users are still able to login to the Grooveshark website with their email address — see this article for further direction, or to contact our support team with any questions.
The total impact of the removal of our Facebook app thus far has been minimal, with less than a 1% impact in overall traffic to Grooveshark from this outage.
UPDATE, 05-13-12: We completed Facebook’s notice, takedown and appeal process for our Facebook Page on Friday, and we’re happy to share that the official Grooveshark Facebook Page has been reinstated.
