Google will shut down Orkut this September to focus on Google+, YouTube and Blogger
As of now, Orkut no longer accepts new users. However, current users will still have fully functional profiles (and everything else) until September 30. Orkut profiles, community posts, scraps and testimonials can be downloaded to users’ computers using Google Takeout (this will work until 2016).
For more on why Google is shutting down Orkut, and what will happen to current accounts and data, check out Google’s own words on the matter at the source links below.
