If there’s one thing that today’s NFL fans need on Sunday, it’s fantasy football.But much to the dismay of many fans, one platform has failed to deliver.

ESPN ran into a big problem over the weekend, when the site’s fantasy sports platform crashed, causing both the site and the ESPN Fantasy Football app unreachable for hours.

The company confirmed the outage, which started around the same time as the first round of the NFL games, on their Twitter account, tweeting: “We are aware of the current technical difficulties. We apologize for the inconvenience and are working to resolve the issue ASAP.”

More than four hours later, ESPN announced that the Fantasy Football platform has been restored. In a statement to Tech Crunch, the company said the crash was caused by a “backend data access issue,” which was “resolved as quickly as possible.”
