Definitely odd. What I'm seeing is three independent messages (they have
unique message IDs).

All three were posted from the same server with the same timestamp.

For example, with the message to which I'm replying, the three copies
have message IDs:

<4AF75869.869.usenet_ceemul@a2central.com>
<4AF75869.2437.usenet_csa2prog@a2central.com>
<4AF75869.14030.usenet_csa2@a2central.com>

Given the mention of the newsgroup names in each of the message IDs, it
looks suspiciously like a bug in that news server, where it is
implementing cross-posting by creating the message separately in each
newsgroup, resulting in different message IDs on a single article in
each group.

When those articles arrive on another news server, they are treated as
three independent articles, and the other server is doing the cross-post
of each (as per the Newsgroups header). Subsequent servers maintain this
arrangement. This means everyone other the the OP's news server is
seeing each article in triplicate.
