Any CDN is a single point of failure and limits your availability to as low as three nines. Although anycast-based CDNs like Cloudflare are much less reliable than DNS-based CDNs, those can do orders of magnitude better.

Why do you think anycast based CDNs are worse than DNS based ones?

They rely on a single network infrastructure as opposed to many independent networks with independent edge nodes where isolating faults is rather trivial in comparison.

Cloudflare: Your status page showed "all systems operational" for over 20 minutes while your primary domain was returning a 502 error. Please change this to update automatically, many other engineering teams depend on you. https://i.imgur.com/qHBM2JW.png

Why even have a status page if it doesn't reflect reality?

Heh, I am reminded of when the control plane at AWS went down... and we had a custom autoscaling config that would query for the number of instances running and scale appropriately... but when the AWS API died... we kept getting zero running instances... So our system thought none were running and so it kept launching instances.... These were SPOT instances and thus only cost like .10 per hour... But we launched like…

> but he created the 201th repo (we had only paid for 200) That's an odd choice of a failure mode. > AWS still refunded all costs... Yeah they should. It was their silly design choice that lead to disclosure of secrets after all. What kind of failure mode is that even. Failing to create the repo would have led to a better user experience for sure. Can you imagine if S3 charged more for private objects and once you re…

>Can you imagine if S3 charged more for private objects and once you reach your count, it just makes them public and posts them on Reddit?

Exactly! What a stupid design UX.

It isn't in their best interest to have a reliable status page. They want status page to contain information about failure only after people know about issues through other means. For the same reason cloud providers don't provide rebates on outages unless you ask for it explicitly.

I think the only way is to have status page operated by an independent 3rd party, but I don't think there's a viable business model for someone to provide such service. Perhaps there might be even a risk of lawsuits against you.

Discord's status page is also down haha

I'm quite surprised Discord's status page is behind Cloudflare. I thought they were using statuspage.io.

They are, but that subdomain is proxied through Cloudflare. If they'd set it to just DNS then it would have still worked.

Once cloudflare.com came back I decided to check out their business SLA, and it's not very encouraging: > For any and each Outage Period during a monthly billing period the Company will provide as a Service Credit an amount calculated as follows: Service Credit = (Outage Period minutes * Affected Customer Ratio) ÷ Scheduled Availability minutes - https://www.cloudflare.com/business-sla/ So assuming an outage affects…

This doesn't surprise me at all - SLA's are widely overrated. No SLA will cover damages incurred by lost business due to an outage. What you likely want is some kind of third-party insurance for downtime caused by outages out of your control - but I'm not even sure this exists.

There are different types of contingent business interruption insurance available. If you're large enough (like Fortune 500), you can negotiate the terms of your policy.

This does exist. It’s just a matter of who pays for it.

not sure what cloudflare costs but compared to the amount our business lost in those 30min, it probably does not matter much.

One thing is not every free or pro plan on cloudflare is personal use. I'm running the web servers, official wiki, and game external resource portal for the most active open source video game on github, through cloudflare, and maybe we might not want our 60 million requests a month website to go down when cloudflare does. Because I can tell you right now our 300 a month budget (that mind you, is capable of covering 7…

If you don’t count this as a personal or hobby project it’s a community project. They don’t have a pricing plan for that so you either have to go pro or go to some other provider who gives you this much for free. Why should a company give you even more pro features for free if you are already getting a lot of things for free?

he’s not arguing that they should. he’s just pointing out the need for your own plan b.
