Network diagnostics

A browser-based estimate of your connection — latency, jitter, throughput, IP/ASN/ISP, and a transparent quality grade. Nothing is stored by sufi.my.

How it's measured

  • Latency: 1 warmup + 8 round-trips to Cloudflare's edge; median reported, warmup discarded. Fewer than 3 successful samples → no claim.
  • Jitter: mean absolute difference between consecutive latency samples (RFC 3550-style).
  • Download: 8 parallel streams × 2 MB (16 MB), total bytes ÷ wall time. Cache-busted; startup transients included conservatively.
  • Upload: one 8 MB generated payload, total bytes ÷ wall time. Discarded by the endpoint; nothing stored.
  • Quality: latency-led grade (excellent < 20 ms, good < 50 ms, fair < 150 ms), capped by download throughput, jitter can only downgrade one step.

Browser-based estimate — not an ISP-grade benchmark. Results describe your connection from this browser.

Runs in your browser. Speed payloads come from Cloudflare's public speed-test endpoints; IP/location lookups use public geo APIs. Nothing is stored by sufi.my.
