Is It My Internet?

Find out in seconds whether the problem is your connection or the website.

Checking your connection

Is the problem your connection, or the website?

Sending seven small requests to our server in Newark, US. It takes a few seconds and downloads almost nothing.

Round trip —Jitter —Failed —Browser says —Your IP —
Full speed test

Round trips from your browser to our server in Newark, US. Not a speed test, and a distant server adds time that isn’t your connection’s fault.

What “Is it my internet?” does

When a website won’t load, it’s hard to tell whether the site is broken or your own connection is. This check answers the second half of that question in a few seconds. It sends a short series of small requests from your browser to UtiBox’s server, times each round trip and counts any that fail.

Use it when pages hang, when video calls keep dropping, or before you restart your router or call your internet provider. If the check passes but one site still won’t open, the problem is most likely with that site, not your connection.

How to use it

  1. Open the page; the check runs straight away. Press Check again to repeat it.
  2. Read the answer beside the circle: whether your connection is the problem. The round trip, jitter, failed requests and your IP sit in small print under it.
  3. If your connection is fine, use the Website Down Checker on the site that won’t load. If it works but feels slow, run the Internet Speed Test.

Understanding the results

Browser says shows whether your device believes it’s online. Treat it as a hint: a device can be joined to a Wi-Fi network that has no working internet. The round trip figure is the median of seven timed requests, sent after a first request that isn’t counted because it has to set up the connection. Variation (jitter) is the average change in time from one sample to the next. Failed requests counts the ones that didn’t get through, and Your IP is the address our server saw.

The verdict follows simple rules. If every request gets through with a median of 600 ms or less, your connection to our server works. A higher median is reported as slow, and any failed request marks the connection as unstable. If nothing gets through, either your connection is down or something on your network, such as a firewall or content filter, is blocking our server. Each bead round the circle is one request: it turns red if that request failed.

Questions

Is this a speed test?

No. It checks whether your connection works and how responsive it is, without downloading anything large. For download and upload speed, use the internet speed test.

Why do the times look high?

They include the distance to our server. A server on another continent adds time that isn’t your connection’s fault.

What does jitter mean?

How much the round-trip time changes between samples. High jitter makes calls and games choppy.

What should I do if the check fails?

Restart your router, or switch to another network such as mobile data, then run the check again. If it only fails on one network, the problem lies with that network or its provider.
