Years late, DT is now satisfied 35G VDSL systems are working well enough to start selling it to customers. In a rare move, DT is also promising a minimum speed of 100 megabits. This is the same service as KPN is advertising as 200 megabits although DT's network probably has longer loops. Based on public information about DT's network, many will not achieve 250 megabits.
35b VDSL is easy to explain. It the same thing as the popular 17b VDSL but uses 35 MHz of spectrum. Alcatel, Broadcom, and others thought the small change meant it would be available in 2016. It's much slower than G.fast, but should work well with DT's existing VDSL.
Something went wrong, apparently with the vectoring software.
(No one is willing to give me a direct answer.) The other problem is that Broadcom is the only chip supplier, something that scares away potential buyers, especially in a time of U.S. blockades.
In England, carriers are obligated to report actual speeds, a good beginning on honesty. I sent a note to Johann Homann, German regulator, asking why Germany doesn't have a similar requirement. I suspect that in private he agrees with me but won't say so on the record.
If the folks writing DT press releases have it right, DT will offer these speeds to ~30M households. That's the implication of the comment "Deutsche Telekom plans to boost 95 percent of the 100-Mbit/s-households to up to 250 Mbit/s by late 2019." Elsewhere, DT has said 80% of Germany will get 100 megabits. It's equally possible the network people haven't explained things properly to marketing. More often than most, DT has been missing deployment targets.
20% of Germany still has some of the worst Internet in Europe, despite promises and subsidies.
