Reddit has stopped working, leaving people unable to access the site.
Users who do manage to get through to the site just see an error message, indicating that the infrastructure underpinning it has stopped working.
The problems are present on both the app and web version of Reddit.
Tracking website Down Detector showed a huge influx of issues reported over the morning, with users complaining they were unable to access Reddit at all.
Problems were particularly focused on the US and Australia, though that is likely to simply be a result of where more people are online.
Earlier in the morning, the company had confirmed another issue that took the site offline.
But it said, roughly an hour later, that the problem had since been resolved.
Reddit's status page, and the official Twitter account that serves the same purpose, was yet to recognise the latest outage at the time of publication.
Reddit, which describes itself as the "front page of the internet", said at the end of last year that it sees 430 million users each month. That was up 30 per cent, year on year, it said.
