After ten years of sparking conversations and forging connections, Google has decided it’s time for us to start saying goodbye to Orkut. Over the past decade, YouTube, Blogger and Google+ have taken off, with communities springing up in every corner of the world. Because the growth of these communities has outpaced Orkut’s growth, Google has decided to focus its energy and resources on making their other social platforms as amazing as possible for everyone who uses them.
Orkut will shut down on September 30, 2014. Until then, there will be no impact on you, so you may have time to manage the transition. You can export your profile data, community posts and photos using Google Takeout (available until September 2016). Google is preserving an archive of all public communities, which will be available online starting September 30, 2014. If you don’t want your posts or name to be included in the community archive, you can remove Orkut permanently from your Google account. Please visit Orkut Help Center for any further details.
