Google+ is no longer available for consumer (personal) and brand accounts

From all of us on the Google+ team,
thank you for making Google+ such a special place.

What happened to Google+?

In December 2018, we announced our decision to shut down Google+ for consumers in April 2019.

Other Google products (such as Gmail, Google Photos, Google Drive and YouTube) were not shut down as part of the consumer Google+ shutdown and you can continue using these products. The Google Account that you use to sign in to these services will remain. Please note that photos and videos already backed up in Google Photos will not be deleted. Learn more

What happened to my Google+ content?

We are in the process of deleting content from consumer Google+ accounts and Google+ pages. This process will take a few months to complete and content may remain during this period. In the meantime, if you previously created content on Google+, you may be able to download and save your remaining Google+ content and delete your Google+ profile. You may also be able to view and delete your remaining Google+ activity.

If I also use Google+ with my G Suite account, at work or at school, for example, how will I be affected?

Google+ for G Suite will continue as a way for people across an organisation to have discussions. Learn more about how we’re continuing our investment in Google+ for G Suite.

If you’re not sure whether your organisation uses G Suite, you can check here. G Suite customers may see some changes to Google+ features related to the consumer Google+ shutdown. You can find more details here or you can talk to your G Suite administrator to learn more.

Let us know, is it okay/good decision or not?
