The original centralized model meant a single regional outage could take down global metrics visibility. Over six months, three teams redesigned the system into a geo-local model that processes and stores metrics closer to their origin, reducing cross-region data transfer costs and blast radius. A federation query layer backed by Elasticsearch routes requests only to relevant geographies, handles partial results gracefully, and returns HTTP 206 responses when a region is unavailable. The new architecture is live in 4 of 5 production regions, with OpenTSDB and HBase as core storage layers and metadata caching keeping wildcard query latency low. ## Full article daily.dev links to this article rather than hosting it.
