I thought data caps for home internet were a thing of the past…
For the past 15 years I’ve had a data cap on home internet, but never had a data cap prior to that.
That’s led me to believe the exact opposite of your observation; unlimited data is a thing of the past and data caps are a thing of the present and future.
They are making an assertion as if it is a statement of fact…and they are, in fact, wrong. That’s ignorant and not helpful for discussion or helpful for understanfing and solving the actual issue. If they had actually asked an innocent question it would be different, but they didn’t. That is why the responses are the way they are.
No, not programmatically. The only way to ‘move’ an instance is for a community of users to create a new community elsewhere and arbitrarily start using it as their preferred community. There is no way to force it and there is no mechanic for moving.
By claiming that the problem isn’t DDOS, you’re just advertising your ignorance. Cloudflair is outstanding for protecting static web content against DDOS, and Lemmy.world is well protected against that. The problem is certain dynamic pages and api calls that can only be rendered from costly realtime dynamic database operations…those are the url that the DDOS attackers are focusing on and those are the kinds of content that cannot be easily protected by cloudflair.
Your premise, though, is still accidently correct. The way to mitigate instances being targeted by DDOS is to spread the user base and community hosting across a vast number of instances so that no one instance is such a rewarding target for DDOS attack.

Are you just talking about dynamic DNS services for one or a few home servers?
There’s always DynDNS, but that’s a paid service. I actually discovered that dynamic IP address service was provided free by Google when using Google Domains as the registrar, so I moved a few of my private domains over to Google several years ago to save myself $55 a year.
Unfortunately, Google Domains is shutting down and all registrar services and existing customer domains are getting moved to squarespace and I’ve not yet been able to determine if squarespace is going to be offering the free dynamic DNS service or not.
