Most offer it, but often not for the regular consumer contracts.
The alternative is to get your ISP to offer you a static IPv6 and a reverse DNS PTR entry for your IPv6, like I asked for in the initial post. Some ISPs do if you offer them more money, some only do if you offer them more money and a legit business registration, apparently a few rare ones do it for free, and some never do it.
Once you got the static IP, you can point DNS directly to yourself, and there's no VPS or anything in between. Browser traffic and so on directly comes to your machine.
While I agree on a practical level, and pragmatism sure is important, long term that workaround still keeps you paying for cloud services and gives cloud companies an easy way to directly man-in-the-middle your traffic. So I'm hoping one day the situation will improve.
I feel like downtimes are a badge of honor for self-hosting in some ways. Being more efficient and minimal means there will be slightly less redundancy and that can be a good thing. Perfect uptime to avoid lost revenue during downtime is a capitalist craze, and not how an ecological project should operate.
It causes way more traffic for the DNS server to use a shorter TTL, so yes, it does incur more DNS traffic. In Germany some providers will disconnect you regularly if you stay connected for too long.
understandable. how dare you change your schedule without advance notice to the cat monarchs of the household :-o
Some ISPs require changes ever 24 hours and will disconnect you if needed. Also, if you set DNS to cache such a short amount of time that you can react to that in 5 minutes, you will incur way more DNS traffic which can become a problem when your site is busier. Also, even if your DNS TTL is set to a super short value, a web search suggests to me in practice there will likely be downstream clients and networks that ignore it and won't really update in such a short time frame.
Even in an ideal DNS setup, you're probably going to have downtimes whenever your dynamic IP changes. If only because some ISPs even force-disconnect you after a while to change your address.
I honestly thought this was a real headline before seeing the source.
oof, that's just sad. i hope people switch, firefox is actually not that bad these days
I think it's still an interesting question whether this feature should be enabled by default (and most people seem to agree it should be).
