The problems began at around 5am on Monday, according to website disruption tracker Down Detector.
The Reddit website is currently showing a blank page with an error message that reads "no healthy upstream".
This typically means that a site is struggling to connect to its backend servers or can't translate its domain name into a corresponding IP address.
Other users have reported seeing different error messages on the site, including "upstream connect error".
The official Reddit status page states that the site is currently running as normal despite being down for thousands of users.
Reddit also hasn't acknowledged the issue on its official account on X.
In the meantime, savvy users have found a workaround to get Reddit working again.
All you need to do is visit "old Reddit," the original, no-frills version of the site. You can access it by typing old.reddit.com into the URL bar on a browser and, if you like it, you can set your Reddit preferences to revert to the original design.
By visiting old Reddit, you can bypass some of the fancy (and sometimes buggy) parts of New Reddit, keeping you connected to your favorite subreddits even during Reddit outages.
Some users even prefer it due to its uncluttered design and the ease with which you can browse lengthier comment threads.
Reddit hasn't experienced a major crash for several years now. However, the site did undergo a blackout last year as a result of widespread user protests over its controversial data policy.
Some of Reddit's largest forums (known as subreddits), each boasting tens of millions of followers, took part in the blackout, resulting in limited access for users.
