digital carbon footprint: how the internet and online services burden the planet
Everyday online activities have a real energy footprint that quickly multiplies in total. In the article, we will look at what digital carbon footprint means, how much energy regular internet use costs, and which activities burden the environment the most. Areas where consumption is growing the fastest and impact is not immediately visible deserve special attention.
On this site you can test your internet connection for free.
We recommend you to lower or stop all other internet activities during the test. In other cases the test results are less precise.
Outputs of this test:
- download broadband speed test - what speed are data from the testing server downloaded by
- upload speed - what speed are data to the testing server uploaded by
- web ping - the time needed to send and receive a small amount of data, quite similar to regular ping, but tested by a TCP packet through the HTTP service
How do Internet speed measurements work?
From the user’s perspective, everything is simple. In the web browser, click on the measurement button and wait. Before starting the speed test, it is important to deactivate all tasks, applications and devices that could use the capacity to connect to the Internet. The results would be affected by that and you would not find out anything, or the conclusions would not have the required notification value.
The technical solution and the background of the speed test itself are complex, but to explain it in a few words and very simplistically, the test simulates a situation in which you download or upload data. The measured values are calculated depending on the speed of these transmission. You can test the speed of up to 30 test servers located in geographically different locations.

How zero trust works: why mere connectivity no longer means safety
Connecting to the internet today is not just a matter of speed but also of trust. Networks handle more and more devices, sensitive data, and services that communicate almost constantly. This is why an approach called zero trust has emerged, where nothing is automatically considered safe. The article explains why this model was created and how it subtly influences everyday internet functioning.
