before the upstart TCP was so widely deployed, and organisations such
as armies, governments and space agencies tend to hang on to these
venerable technologies for a long time.
It seems however that ESA is finally abandoning X.25 for their world
wide network - the OSI (there's a another venerable near dead
technology) stack that ESA uses will be validated for use on Solaris
10 but NOT over an X.25 transport.
TBH I don't think there'll be too many people crying - X.25 has so
many configurable options that the number of different ways to break
a link is huge. And interestingly, many of these ways will only break
the link under certain circumstances, thus making debugging even more
