Mesh Architecture & Ground Sites

The UC10 platform operates across 5 Canadian ground sites in a decentralized mesh architecture, eliminating single points of failure.

Each site — Toronto, Ottawa, Calgary, Vancouver, and Montreal — runs its own PostgreSQL/TimescaleDB node. Data is replicated bidirectionally across all 5 nodes using logical replication slots. Any node can serve as the primary for its region, enabling autonomous operation during WAN partitions.
