* An edge,

so when you make a change it's replicated to all regions?

No. A DO only exists in a single edge location. That's the entire point of Durable Objects.

D1 will replicate soon, but doesn't do so yet. My understanding is that it will replicate to ~5 locations and keep these locations fresh.

It's weird because all their marketing says it's distributed but it's not really

Distributed for thee but not for me
