In 2007 I researched the status of each of the addresses in 14/8,
which at that time was reserved for the gateways between x.25 and
IPv4, as a part of reclaiming that /8. A large number of the addresses
were still in use for a government network in Sweden (a labor
exchange, I believe) and they were returned after the gateways were
renumbered. Deutsche Telekom and BT were also still selling X.25
circuits at that time.

Looking at BT's current published pricing, I think they still sell
X.25 circuits:


I suppose people still use X.25 and the telcos at least cover their costs.
