I’d like to add that Dutch state news broadcaster NOS now offers Teletext though SSH. Just type `ssh teletekst.nl` and you can browse through all their pages.
They fully revamped their Teletext backend a couple of years ago to their own solution. They had archaic hardware still, and had to fly in some one from the UK (fully pensioned and well) to service it
If you're not setting up your own instance, make sure to help fund the instance you are using. Maybe it's on the about page or DM/Mention the server admin! They can tell you where to donate
I'm not really positive about the community made generator. The spec itself is great, but that's where it stops. Code quality is low of the generated clients and servers, the handlebars templates makes it hard to develop for and don't get me started about the PR reviews. Basically nothing happens.
We've given up and started to create our own generator. Even this is a hard thing to do as the available parsers in our language are horrible too.
