Phoenix, AZ: CloudFlare's 64th data center

This post announces the launch of Cloudflare's 64th data center in Phoenix, AZ. It details the importance of regionalizing traffic to improve performance and reduce latency, especially for users outside major interconnection hubs. The post explains the concept of 'hot potato routing' and uses measurements of BGP community tags from Tier 1 providers (NTT, TeliaSonera, Tata Communications, Cogent) to illustrate the low level of local interconnection in Phoenix compared to the San Francisco Bay Area. The launch of the Phoenix data center is presented as a solution to bring content closer to local audiences.
