the region for your space and thus where your data is stored
to optionally lock your space - which stops replication for the http state channel. Typically done for governance/sovereignty requirements. It reduces redundancy significantly.
DESIGN
mydigitalstructure uses a "http state channel" to replicate state changes to multiple regions, based on single on-region http request.
It is self-organising - in that if any one region should go offline - using DNS level TTL switching and other region will take over. When the offline region comes back online it sends a request out to find the region with the best knowledge of the missing state information and requests a "replay" of the missing state. Once this is complete, it announces itself as available.
