DeviceOK measures browser-visible connection hints and HTTP round trips to DeviceOK. Throughput samples use small HTTP transfers to DeviceOK and are useful for quick comparison, not ISP speed certification. This is not an ICMP ping, local-network scan, or VoIP/RTP jitter measurement. A public IP can represent a VPN, carrier gateway, proxy, or shared NAT rather than a physical device address.
Private by design
Only small requests to DeviceOK are timed.
Use the result as evidence, not a guess.
This test checks
- Repeated HTTP round-trip timing
- Observed timing range
- Timing standard deviation
How to read it
This is HTTP timing variation to DeviceOK, not certified VoIP/RTP jitter or ICMP ping.
Wi-Fi congestion, routing, server distance and browser scheduling can affect the result.
