zip codes are not geographic areas, they are a collection of mail delivery points. Sometimes those points are not geographically contiguous or may overlap
This is the third big release this week (along with a Postgres Pooler and a Logging Server).
If you're wondering why there are so many, we generally "build for three months" then do all of our big product announcements in a "Launch Week". We're 2 days into this Launch Week so there will be a few more releases to come.
If this sort of thing interests you but you can't afford a multi-million dollar build I'd recommend checking out Theron Humphrey's work building a modern lakeside home in Montana (https://www.thiswildidea.com/casa). He built a simple, modern and affordable (think low 6 figure) home and did a good amount of the work himself while sharing info on the process. Apparently he's embarking on a new build this year in Arizona and sharing more in-depth info on his youtube.
