NetCheck

About NetCheck

NetCheck answers one question every South African has asked at some point: is it my internet, or is it them?

We built NetCheck as a free, independent toolkit for anyone whose internet is acting up — at home, at work or on the go. Instead of just showing numbers, our tools explain what the numbers mean and what to do next, in plain English.

What we offer

  • Internet speed test — download, upload, ping, jitter and lag under load, measured against local servers, with a data saver mode for mobile users.
  • Connection diagnosis — finds the most likely cause of slow or unstable internet and gives you a prioritised fix list and a report for your provider.
  • What’s my IP? — your public IP address, provider and approximate location.
  • Is it down? — checks if any website is down for everyone, or just for you.
  • Guides — practical help on Wi-Fi, choosing a package, power backup and more.

Our principles

  • Free and no sign-up. The site is supported by advertising, which we keep away from the tools themselves.
  • Independent. We don’t sell internet packages and we’re not owned by an internet provider.
  • Private. Speed-test history is stored only on your own device. See our privacy policy.
  • Honest. Results are estimates. We explain how each tool works so you can judge the results yourself.

How the speed test works

Our speed test uses Cloudflare’s open-source speed-test engine and global network, which has servers in Johannesburg, Cape Town and Durban. If those servers can’t be reached, NetCheck automatically falls back to its own backup test servers.
