Choosing acceleration for cross-border sites: test actual visitor regions
Compare routes using visitor regions, origin location and real transaction endpoints.

One local test does not represent international users
International sites serve different regions and access networks. Gather visitor locations and peak periods, then measure DNS, TLS, time to first byte and page completion before selecting a route.
Compare public pages and transactions separately
Fast cached images do not prove that carts, sign-in and order APIs are fast. Dynamic requests depend on origin distance and application work. Keep cache-hit and cache-miss measurements separate.
Account for legitimate partner traffic
Region controls must account for users and service partners. Payment callbacks, crawlers and corporate proxies may use locations different from the buyer’s. Validate each dependency before broad geographic restrictions.
Retest with consistent business metrics
After a route change, compare success, timeouts, origin requests and order completion for the same regions and periods. Confirm deployment-specific registration and content requirements separately.
