Check if Cloudflare DNS 1.1.1.1 is operational.
Could be. Also trying Cloudflare DNS, but I'm running into problems too
They seem to be indicating a service disruption, curious about the reason https://www.cloudflarestatus.com/
I wasn't able to reach any DNS servers—no DNS data arrived at all—but routing stayed intact with IP addresses. I switched from Cloudflare to Google (using /flushdns) and then to OpenDNS, but both returned no response. After rebooting my computer and testing on a Mac that only uses Google DNS, the issue disappeared. I also rebooted my router, which now routes me through a different path and restored full DNS access. It seems there was some unusual redirection of popular DNS traffic, which could reveal detailed browsing patterns for many users.
System appears operational. Connection restored via Wi-Fi on device.
It was incredibly quick. Checking the status page shows their DNS timeouts and the implementation of the fix are just a second apart... 0_0
I performed a traceroute to 1.1.1.1 (Cloudflare public DNS), 8.8.8.8 (Google public DNS) and 208.67.222.222 (OpenDNS public DNS). The paths changed significantly before and after I rebooted my router. I would have liked to save this information, but I restarted the machine after testing but before rebooting the router. It would have been fascinating to see.
In Windows you could have simply configured the main DNS to 1.1.1.1 and the backup to your ISP’s DNS instead of relying on Cloudflare. This way, if the service fails you’d still maintain network access. (Or even better, set up multiple static DNS entries in your router—DD-WRT supports three: 1.0.0.1 (Cloudflare), 8.8.8.8 (Google) and your ISP’s.)
