Pinterest is for those that love to share photos, and when the photo-sharing social network encounters problems such as login, and not being able to upload photos, its users are then left in the dark. If there were an outage right now its users would not be able to share their photos on their profiles or to blogs around the world.
If you are using Pinterest you will know it is available on desktop and mobile devices, and when Pinterest.com goes down it does not mean the app is down as well. But if it is both that are down then you would call it a total widespread outage.
Main Pinterest issues could involve not being able to like a pin, upload a photo, the whole website not working, now and then even the boards do not work correctly. You will be able to see other users posting their problems below, if you have any please do list them.
