Individual telecom broadband connection experiences?

In the planned Saar-Pfalz district, Deutsche Glasfaser is partially rolling out FTTH. Find out exactly in which towns this is happening. However, this limits the choice of properties. Or ask how much just a line would cost you.

Yes, I have seen that they are in the expansion phase in some municipalities. But there are not many. The property we have in mind is in another municipality.
I'm also looking for alternatives because the provider that is expanding there (Inexio) is EXTREMELY criticized in Google reviews. Of course, it’s not guaranteed that their FTTH performance is as bad as their DSL, but if I can, I’d rather avoid them.

Google reviews, after all. It will definitely be better than DSL. But since they are not expanding there at the moment anyway, it doesn’t help. However, one could still inquire in parallel with Telekom.
