Personally I had thought all of the public x.25 networks like Sprintnet/Telenet, Datapac, etc. had been shut down at the beginning of the last decade. I'm guessing these must be private networks still running x.25. It would be interesting to hear from anyone not in the US or Canada if their x25 networks are still up - can you still dial into a PAD? Here in the US you used to be able to dial into a 1-800 number and login with phones/phones (or something like that) to get a directory of local dialups in your area which you could then call locally (so you wouldn't get hit with long distance charges).
I remember a presentation on x25 security from not too long ago that articulated this very point: "Everybody “forgot” about their X.25 direct links":
