Looks like Cloudflare is experiencing a pretty widespread outage that’s affecting a number of websites at the moment.

From an article by Les Pounder and Stephen Warwick on TomsHardware.com:

In the last few minutes Cloudflare has confirmed it is aware of a major issue affecting its Global Network, which is causing widespread internet outages ranging from platforms like X (formerly Twitter) to ChatGPT, and, ironically, Downdetector. A wave of other websites and services are also experiencing outages.

Cloudflare is working on a fix, with updates available on the CloudflareStatus.com website.
