Social media platform Reddit experienced an outage this afternoon at around 12:20 p.m. PT (or possibly even earlier), resulting in thousands of users being unable to access its website and app. After four hours, it appears to be working again.

Reddit confirmed it fixed the issue and is monitoring the results, according to its status page.

We discovered the outage ourselves when attempting to visit the homepage, which displayed a black screen with the message: “Upstream connect error or disconnect/reset before headers. Reset reason: connection failure.” On the iOS app, we only saw the dead Snoo head, Reddit’s alien mascot. 

Over 47,000 users reported problems on Downdetector.com and many users took to X to voice their complaints, sharing images of the same connection error page that we encountered. 

TechCrunch has reached out to the company for comment.
