# Why is the website blocked?

A website can be blocked because it falls under a category that is blocked in the current mode of your switch, or because we have not (yet) categorised the website.

**Website not known**
In modes 1 and 2 we block websites that are not known to us. So it can happen that a teaching method is blocked. You can have us add this website to a category. Let us know via the chat (bottom right).

**Look up a website**
Want to know which category a website belongs in? You can easily look this up with our [handy search function](https://www.myndr.nl/nl/school/standen/websites-zoeken/).

**Overview of categories**
To give you an idea of the categories and which types of websites belong in them, you can look at the [Overview of categories](https://www.myndr.nl/nl/school/standen/overzicht/) page.
