⚡ Internet Speed Test

About this Speed Test

A speed test measures how fast data moves between your device and a remote server. Four numbers matter: download (how quickly you pull data), upload (how quickly you push data), ping (round-trip latency), and jitter (latency variation — critical for voice and video calls).

ZakGT Speed Test runs against our own servers at api.zakgt.net (Singapore). We use 2 parallel TCP streams for download and a 1-second sliding window for live display.

Results are saved locally in your browser’s localStorage only — up to 20 runs. A summary (speeds + ping, no IP address) is also counted globally so the live stats counter above stays accurate. We do not log IPs from speed test requests. See our Privacy Policy.
