Internet Stability Test

Is your connection steady, or does it drop and spike? This test watches it second by second for up to five minutes and shows exactly when things go wrong.

Longer tests catch problems that only happen now and then. Keep this tab open and in front while it runs.

Choose a length and press Start. The chart shows your connection second by second.

How it is measured: once per second the test times one small HTTPS request to Cloudflare's nearest server and subtracts the server's own processing time. Every request counts, so a single slow one shows up as a spike. Seconds when the tab was in the background are left out. A second where nothing comes back in time counts as a dropout. A spike is a response more than twice your typical ping plus 20 ms. Jitter is the average difference between consecutive seconds. The stability score starts at 100 and loses points for jitter, spikes, dropouts and a rising trend. Results describe the path to Cloudflare, which can differ from the path to your game or call server. Nothing is stored.

Need a quick check first? Try the ping and jitter test or the full speed test.

Why test stability?

A speed test is a snapshot

It measures a few seconds of maximum throughput. A connection can pass that and still drop out ten times an hour.

Calls and games need steadiness

Real-time apps care less about top speed and more about every second arriving on time. One long spike is enough to freeze a call.

Problems come and go

Interference, busy neighbors and failing equipment show up intermittently. A longer test gives them time to appear.

Common questions

What is the purpose of an internet stability tester?
An internet stability tester measures and analyzes the stability and performance of an internet connection to identify any issues affecting its reliability.
How does an internet stability tester work?
By sending data packets between the user's device and testing servers, an internet stability tester evaluates factors like latency, jitter, and packet loss to provide an objective assessment of the connection's stability.
Why is internet stability testing important?
Internet stability testing helps identify connectivity issues, optimize performance, support business operations, and enable users to make informed decisions about their internet service providers.
What are the benefits of using an internet stability tester?
Using an internet stability tester enhances user experience, improves productivity, provides troubleshooting assistance, helps evaluate service providers, and future-proofs connectivity.
How can I improve internet stability?
Some tips to improve internet stability include upgrading your router, optimizing the Wi-Fi signal, using wired connections, updating firmware and applications, and contacting your ISP for assistance.
