Upstart online retailer Jet.com appeared to be suffering some website trouble early Saturday.
The company—which is positioning itself as a major challenger to Internet retail behemoth Amazon.com—saw its site return an error message to users that tried to access it. The mobile application was also reported by some users to have gone down.
The source and the extent of Jet.com's trouble wasn't immediately clear. An inquiry placed by CNBC to the company was not immediately returned.
