Isn't HN on Cloudflare? How are we reading about a CF outage on a site that runs behind CF?

Seems to be intermittent, and perhaps dependent on which POP you are hitting. I have been getting PagerDuty alerts that are flapping between triggered and resolved.

for our sites behind cloudflare, it seems to be a routing issue (among possible other things) - some visitors can still access the sites, others can't. traffic went down roughly 60%.

We have several websites running behind Cloudflare. Only one out of our 8 or so seem affected

I've seen the "checking your browser" on HN message quite a few times, especially when I use a VPN, and I'm pretty certain it's the CF one.

Maybe it's turned on selectively for high traffic / bot situations?

How would that kind of disruption happen? Someone else also anycasting the CF IP addresses?

This seems like a partial outage, likely region-based. We have a large number of sites routed through Cloudflare and I can access all of them from home, but our HTTP monitoring software reports the sites as down.

"Cloudflare is observing network performance issues." not just performance issues, our entire website is unavailable because of it. edit: availability has been alternating between available and unavailable

It's not their fault as accidents happen to everyone. You should be prepared for such a scenario and for many others too.

You are right, accidents happen to anyone. I cannot really be prepared for Cloudflare to go down though. What are my alternatives? Turn it off and route traffic to our servers directly? The DNS propagation takes longer than it just took for our website to be available again.

It’s caused my site monitoring via PagerDuty to go insane, with texts sent every few minutes.

One of the weirder leaks I've seen, 8.8.8.8 and 1.1.1.1 are both down for me, but everything else is working fine.
