Cloudflare, 1.1.1.1 and Discord down: Problem causes errors when accessing thousands of websites

Due to a problem with the CDN provider Cloudflare, some services such as Discord are currently down. In addition, some websites supported by Cloudflare are currently not accessible and display an error message.
We already had the problem a few months ago, where Cloudflare caused problems with websites. Now there is another problem – Discord is also affected, as you can see on twitter wrote. In addition, Cloudflare's DNS service (1.1.1.1) is currently experiencing problems and is no longer resolving properly.

Also Google DNS, OpenDNS in addition to Cloudflare down
Update 2: It seems that this was a larger problem - and not just one with Cloudflare. Google DNS and OpenDNS were also partially unavailable and did not resolve the pages correctly. Since numerous websites depend on and use these DNS servers, Github, Discord, Spotify and many other sites were also unavailable.
Update 3: Cloudflare says that a router in Atlanta caused a problem that has since been resolved. Cloudflare CEO Matthew Prince via Twitter to know. However, we are skeptical whether it really is that. After all, it felt like the failure affected half the Internet and not just the Cloudflare DNS servers. We'll probably know more in a few hours.
Update 4: There seems to be a small hiccup every now and then. So the problem does not seem to have been resolved yet. If you are also unable to access some websites, proTry out some alternative DNS servers - we have listed them for you above.
