How do we check if Costco is down? We determine if a website or app is down based primarily on visitor reports, from people like you. This often lets us detect a problem with Costco before they have publicly posted about that outage to their users. When you submit a report using the buttons at the top of this page, our system combines them and determines if they indicate a problem with Costco.
Let other Costco users know what problem you are having with the service, app, or website.
