Other than Instagram, Pinterest is the largest photo-sharing network out there; you can share your photos via the web or through mobile apps. If Pinterest were down right now millions of photos would not be shared to the network, and the impact would leave users very unhappy indeed.
Not being able to upload your pins, comment or like other pins etc would most certainly stop you in your tracks. Pinterest problems other than outages would include login issues, pages running very slowly, as well as apps now and then crashing or not loading properly.
On-screen Pinterest messages have appeared in the past on the lines of “Something Went Wrong! Sorry. We’ve let our engineers know.” This is what will be shown when Pinterest is down. If you are having any Pinterest problems no matter how big or small please do report them below with your location.
