Key Terms Explained
- Latency
- Round-trip time to a server in milliseconds. Under 50 ms feels instant; over 150 ms is noticeable in calls.
- Jitter
- Variation in latency between packets. High jitter breaks voice and video even when average speed looks fine.
- ASN
- Autonomous System Number — the identifier for the network operator that owns an IP range.
- DNS TTL
- How long resolvers cache a record before asking again. Lower it before you plan a migration.
Why this matters
When something is slow, the first useful question is where. A quick measurement of throughput, latency and the route your request takes turns a vague complaint into a ticket someone can actually act on.
Frequently Asked Questions
How accurate is Internet Speed Test?›
It measures what your browser can see from this device, so Wi-Fi interference, VPNs and background downloads all affect the reading. Run it twice for a fair average.
Does Internet Speed Test work on mobile phones and tablets?›
Yes. The layout is mobile-first and tested on iOS Safari, Android Chrome and every current desktop browser, with tap targets sized for thumbs.
Does Internet Speed Test collect my IP or location?›
The lookup provider receives the query needed for the check. Review the tool notice for the provider and input sent.
Is my data safe when I use this speed test?›
Data handling varies by tool. Read the notice above the workspace to see whether your input stays in the browser or is sent to a named provider or service. Avoid entering sensitive information unless you understand that tool's handling.
Why does my result differ from my ISP's advertised speed?›
Advertised speeds are line maximums measured over Ethernet. Wi-Fi, older routers and peak-time congestion typically account for the gap.
How is Internet Speed Test different from other online speed test tools?›
It does one job without pop-ups, forced sign-in or interstitials, and remembers your settings between visits so repeat work takes seconds.
Can I share this speed test result with support?›
Yes — export the reading as JSON or take a screenshot to attach to an ISP or IT ticket; the timestamp and server used are included.
