reason: You want to use dynamic wildcard SSL certificates via Letsencrypt. Because they need to be validated via DNS. reason: You want to use anycast (rent cheap VPS servers that support BGP) The anycast managed services that exist will takes days to sync all servers, thus you can't use DNS validation with Letsencrypt. Solution: Run your own Anycast ... That said, anycast is overkill, because DNS has caching built in to it's protocol, if the user has looked up your IP once, it will be cached on the user machine next time he/she looks it up. And if you have a fairly popular domain, it will also be cached at the ISP or whatever DNS resolver the user has.
