New names wasn't serious problem from technical part, I see most
problems from human resources part. I.e. all changes required
to adapt new names are technically simple, but cause bug troubles
and confusion to people.

MSK/MSD was born and used initially on Moscow computers with Unix-like
OSes by several developer groups (f.e. Demos group, Kiae group).
In those times we don't have any serious connectivity to
the rest of the world, so they was used internally.
Next step was UUCP network, Relcom predecessor (used mainly for Mail),
and MSK/MSD actively used there.
Next step was Internet connections which inherits tz conventions from earlier

WSU is obviously homemade. Don't relay match on Glasnet things,
this provider comes here only recently, better look at Relcom
postings (most of *.ru, *.su domains without any 'glas' prefix),
Relcom is oldest Internet provider here.

For Russsian language Usenet you can look at relcom.* hierarchy.
Don't expect to find many zones there, because
most of world-spreaded Newsreaders don't know anything about Russians.
BTW, relcom.* hierarchy can give you more hits because Mail/News
gateway still used here.
If you'll find some Russian Mail lists archived, it give you more
success. I know lists, but don't know any archived.
I can send you Date:'s from my home Mail folders, if it can
be considered as proof.
