Cloudflare: Is anyone else seeing DNS outages?

113 points by euph0ria ↗ HN
Seems that all our domains on Cloudflare are down. They can't be resolved and we can't even access www.cloudflare.com from several locations worldwide.

I'm seeing this too, I can't even load the Cloudflare website.
1.0.0.1 and 1.1.1.1 are down for me for providing DNS.
We are. We suddenly can't pull up any of our properties that use cloudflare DNS.
We are experiencing issues with DNS, Discord seems effected as well
Yes, can confirm I am seeing the same behavior. Other members on my team in other regions are able to resolve addresses - seems to be hit or miss to a degree based on location.
yes and funny enough, downdetector is down. started doubting my network until all the same outages confirmed on my mobile link, and mxtoolbox couldn't get a response either.
(comment deleted)
I'm getting some. 1.1.1.1 isn't responding to any DNS requests for me.
Yes, experiencing the same issue from the UK.
And me. (UK)
Same (UK) some sites work, some others not. Thought it was just me.
using dig with 8.8.8.8 for discord.com and downdetector.com, I'm not seeing answer sections?
Yep, github actions failing because of this too.
Yea, this is what brought me here. It had to be right when I was trying to debug an action didn't it.
All my tests passed. The only explanation must be because Github Actions is being affected. My tests would never pass otherwise.
downdetector is down. Discord is down. Cloudflare is down.

Looks like a major DNS attack.

Hanlon's razor applies here.
Well I just rebooted my modem, but modem + router checked out (I know the IPs). Rebooted the Pi-Hole, seems to be back up now. Cloudflare is the only DNS my Pi-Hole forwards to. I think I will add another, now..
Which ones are you going to add? Just curious. :)
I've been happily using NextDNS for a few months now on my mac and iPhone with no problems so far :)
I've used 4.2.2.1 extensively in the past, and never had any issues. 4.2.2.1 through 4.2.2.6 are run by Level 3
Oh, I've heard about it, but I don't like to use it because it returns a search page filled with ads for nonexistent domains.
I went with Comodo, but Level 3 also seems reasonable. Sorry, I wasn't checking replies.
I can't get to chess.com.
Lichess is up (and also better)

Both the primary and the secondary going down is a killer. It's enough to make me switch out the secondary to a non-cloudflare DNS.

Even when the secondary works the performance is pretty miserable. Adds about a 1s latency to each DNS resolution while it wait's for the primary to fail.

Yep. I quickly logged into my home Pi-hole and unchecked both IPv4 Cloudflare DNS servers.
First twitter and now this....
Our AppBeat monitoring is reporting Cloudflare issues too.
Same here DNS is not resolving for several domains and subdomains.
Same here, DNS domains and subdomains not resolving.
I can't access my own VPS nor Digital Ocean (which takes care of DNS). Good to know I'm not the only one with issues, at least.
Just had a sales call w/them the other day and expressed concern about sending domain authority over to them- this doesn't give me the warm and fuzzies.
