Week of 20 July 2026: 3 different providers were fastest across the 4 regions we measure from, and nothing moved by more than a quarter against the week before. Who led each region last week? Region Fastest p50 TTFB Uptime Asia (Tokyo) fireworks 16 ms 100% Europe (Germany) nscale 98 ms 100% South America (São Paulo) openrouter 56 ms 100% US (Central) fireworks 27 ms 100% What changed by more than 25%? Nothing did. A quiet week is a result too, and reporting it is the only way the noisy weeks mean anything.
