How fast data reaches you. Critical for video calls, cloud apps, and large file transfers.
How fast you send data. Essential for video conferencing, cloud backups, and VoIP.
How long web servers take to respond. High latency = sluggish cloud apps and slow page loads.
How fast domain names are looked up. Slow DNS makes every website feel slow — even on fast connections.
Confirms your public-facing IP address. Useful for troubleshooting VPN, firewall, and remote access issues.
Weighted composite score (0–100) across all tests. At-a-glance understanding of your internet quality.
The test uses real HTTP requests to major services (Google, Cloudflare, Microsoft, Amazon) and measures actual browser network timing APIs. It's a reliable indicator of real-world performance, not a synthetic benchmark. For a full diagnostic including bufferbloat, jitter, and VoIP MOS scoring, contact FCT.
For a small office (5–15 users), 50–100 Mbps download and 15–30 Mbps upload is generally sufficient. VoIP and video conferencing add about 0.1–2 Mbps per concurrent call. The health check score helps you interpret your numbers — 85+ is excellent, 65–84 is good, below 65 may need attention.
The browser quick check covers speed and latency. Bufferbloat, jitter, packet loss, traceroute, and VoIP MOS scoring are available in the full FCT diagnostic. Request a full diagnostic — it's free and takes about 5 minutes.
