I've tried this across multiple Tier 1/2 servers with the same result.  All those DStar Repeaters, Hotspots and Users are still there, connected and sending the same info they were before.  But it's no longer fed by default to those stations connected to the Tier 1/2 servers.

As I said before, there is no unilateral control of APRS-IS. There are
various server softwares in use and dozens of server administrators.
There is no single group or leader running all of them. There must be
some other explanation for the behavior you're seeing.

Instead of speaking generally, maybe you could give some examples of
the disappearing data. How about:
1. The name of the object(s) that disappeared.
2. The callsign of the station submitting those objects.
3. Your igate callsign.
4. The server your igate is currently connected to.
5. The other server(s) you tested in the process of identifying the
described problem.

By the way, port 14580 is not a "default feed". It is a "filtered
feed". The filters are additive, so with no filter, you receive no
data (except messages). For an igate, no filter is optimal because you
really only need messages and their associated position reports passed
back to RF. For APRS clients with a human sitting in front of them,
range filters are common, so that the client map shows nearby
stations.

For what it's worth, I haven't blocked any Dstar data on my APRS-IS
server, nor have I been requested to by any other server operator. I
did, however, run a software update that could potentially affect the
data you receive.
