Our upstream ISP also has such a reciprocal secondary, too.

We actively sought reciprocal secondaries, and offered and received
reciprocal query hosts, from other regional ISPs when I was CTO @ ADN.

We saw it as "strengthening the regional Internet".

So our users used CTSnet as their tertiary NS, and CTSNet used ours, FE.

Of course, not CTS/CARI and ADN are all AIS, so the point is moot.
