Extended test (approximately 525 MB maximum download data)

Optional isolated streaming diagnostic: downloads approximately 20 MB, separate from the official speed score. Some browsers may restrict Web Workers or cross-origin streaming.

About Speed Measurements

The gauge spans 0–1,000 Mbps. This test uses Cloudflare’s edge and a capped progressive sample plan. Data usage can be lower if testing finishes early. Advertised gigabit service is not a guarantee of gigabit speed over Wi-Fi.
