Some countries monitor Internet traffic or use censors that prohibit or ban certain content on the Internet.
It would be conceivable for Caterna to fall under this scheme in some countries.
Another option is that the operator of the Internet connection (such as a hotel – see also, Caterna Hotel) prevents the Caterna page to load.

However, we already have patients who used the therapy in a foreign country and they could easily use the caternal therapy from there.
