Network Latency Test

What Does This Tool Do?

The Network Latency Test pings public CDN and marketplace endpoints from your browser and reports round-trip time in milliseconds. Use it to verify that your VPN exit or proxy location does not add excessive delay when accessing seller dashboards, ad managers, or listing tools.

This is a latency probe — not a bandwidth speed test. Lower milliseconds mean snappier page loads and API responses. Switch between Global (infrastructure) and Marketplaces (seller-relevant hosts) tabs to compare routes.

Frequently Asked Questions

What does this test measure?

Round-trip latency (ms) to each endpoint — not download speed or bandwidth.

Why does latency matter for sellers?

High RTT through a distant VPN exit slows Amazon Seller Central, Shopify admin, and ad platform dashboards.

What is a good latency number?

Under 100 ms is excellent; 100–300 ms is usable; above 500 ms may feel sluggish for daily operations.

Why do some endpoints show failed?

Firewalls, regional blocks, or CORS/network policies may block the probe. Try a different VPN exit or network.
