I'm not sure that 198.32.0.0/16 was ever advertised. EP.NET runs a
registry for exchange points and other people that Bill feels like
helping out and assigns from that number range; since the /16 covers
many varied applications and organisations all over the planet, it
seems unlikely that a /16 would do anything useful.
I have no problems reaching FLAG.EP.NET (198.32.4.13), DOT.EP.NET
(198.32.2.10), both of which live in subnets numbered from
198.32.0.0/16 and administered by EP.NET directly.
A quick RIS query suggests that none of the RIS probes have ever seen
an advertisement 198.32.0.0/16.

There are a number of prominent DNS servers numbered within
198.32.0.0/16; however, for various reasons a noticeable number of
network operators take the position that all routes within that /16
are necessarily bogons, since it was originally designated for use in
numbering exchange-point fabrics and those blocks ought properly not
be advertised.
I take no philosophical position on any of that (it's far too sunny
and verdant here to form that kind of opinion here this afternoon),
and in a similar vein apologies for any historical inaccuracies I may
have inferred above. However, from a purely operational perspective,
you may want to check that the specific subnets of 198.32.0.0/16 that
you are interested in have not been filtered by your transit providers.
