And the UBC X.400 code tied together "cdnnet" (spelling/punctuation long 
forgotten), a collection of mostly academic sites in Canada that ran an 
X.400 mail network over X.25 (and for which UBC contributed quite a bit of 
code to BSD4.[23] as I remember).  X.25 was a big thing in Canada 
throughout the 1980s and early-to-mid 1990s, in the form of 
the Datapac network, run by the ILECs of the day.

There was a semi-serious conversation in the mid-latter 1980s about 
whether the TLD for Canada might be '.cdn', since that was what the X.400 
mail network used to flag its participant's addresses (ala .bitnet) in the 
ARPA/Usenet world.
