Is Cloudflare DNS acting up for other people?

[atxcyclist]

My internet stopped working a while ago, couldn't find the cause after a bunch of troubleshooting. It turned out when my router defaulted to my ISPs supplied DNS, my internet was working again. Is anyone else using 1.1.1.1 and 1.0.0.1 DNS getting random errors or just nothing at all when they try to load pages?

not I. I use Cloudflare as my main DNS.

Run a traceroute to 1.1.1.1 and 1.0.0.1 while using your ISP’s DNS servers.

My internet stopped working for a few minutes today and I indeed use 1.1.1.1

Don't know if that's related

It is now working again, I'm just glad it didn't fail when I had my Zoom meeting earlier.

I spent most of the day on the road so I missed this occurring. I normally use Cloudflare (1.1.1.2)  as my preferred and Quad9 as my alternate DNS. I used OpenDNS for years but moved away from it when Quad9 came on the scene.

Interesting, I'd never heard of this. Any appreciable differences in latency between Quad9 and Cloudflare? I use the Cloudflare DNS for security/spam rejection, but it's also a ton faster than my ISPs defaults.

ISP defaults, in my experience, have always been awful on top giving your ISP more ways to get info and possibly make money off you. That said, I prefer Cloudflare, overall, but you could use most of the bigger known "free" DNS providers without really noticing a difference. Some, obviously, provide more in the way of security or blocking malicious domains, etc. OpenDNS while it was superior to my ISP DNS wound up being troublesome. Quad9 was definitely faster than OpenDNS when I switched over. The same goes for Cloudflare, IMO, compared to OpenDNS. Numbers are numbers but there's also some subjectiveness in real-world use, IMO. I use both Cloudflare and Quad9 just for redundancy where if there's an issue with one my backup is a different provider altogether.

 

I did a quick resolve time comparison between a few DNS servers:

1. Adguard (176.103.130.130) - Resolve time: 66 ms
2. Cloudflare (1.1.1.1) - Resolve time: 76 ms
3. Google Public DNS (8.8.8.8) - Resolve time: 73 ms
4. OpenDNS (208.67.220.220) - Resolve time: 65 ms
5. Quad9 (9.9.9.9) - Resolve time: 66 ms

All pretty close with Cloudflare being the straggler. Between Cloudflare & Quad9 I can't honestly perceive any difference in use.
