why not host your own

I’ll first have to research how, but at no point will I consider myself as reliable as some professional provider like Cloudflare.
On the other hand, Cloudflare is kind of becoming the internet with all the centralization. Imagine if Cloudflare and AWS completely went offline at the same time. The internet would be fairly quiet.

OK, now I am even more interested. dig doesn’t return an A record:

$ dig glauca.digital a

; <<>> DiG 9.20.27 <<>> glauca.digital a

Somehow, it does work in a browser. I tried different DNS servers as well (including NextDNS which I use in a browser), none returns an A record (or AAAA). So, naturally, I am curios what IP the browser uses. Since it clearly works, I tried ping just so that I could see the resulting IP, and figure out where it’s coming from.

$ ping glauca.digital
ping: glauca.digital: No address associated with hostname

Great. That makes absolutely no sense at all. Where is Firefox getting the information from?
So I went to about:networking DNS tab. The address field is empty. I am just typing this as I test. It’s just cache in my browser.

I guess that would answer on reliability question. At least their nameservers still resolve to IP.

What happens when you try?

I plan to perhaps, just maybe, I am not sure, to try self-hosting an email server. But I’ll need a good uptime.
Although I am really scared about security.

Ooooo, that looks nice.
