Built, no, definitely not voluntarily¹, Ethernet is the only non-legacy thing surviving for new installations for anything more than short range (few kilometer) runs. InfiniBand, CPRI and SDI are dying too and getting replaced with various over-Ethernet things, even for low-layer line aggregation there's FlexE these days.
¹ some installations are the exception confirming the rules; but as a telco sinking more money into keeping an old SONET installation alive is totally the choice of last resort. You'll have problems getting hardware too.
Disclaimer: I don't know what military installations do.
It is a nice interconnect. It is a shame that the industry does not revisit the idea of connecting all components of a computer over infiniband. Nvlink fusion is a spiritual successor in that regard.
Yes, IB hasn't died… yet. But the writing's probably on the wall with Ultra Ethernet; the corporate development of Mellanox (now nVidia) is not a great sign either.
(Also you don't use IB for 1800km WAN links.)
FWIW I actually run IB and think it's a nice interconnect too :)
Used, maybe, but [citation needed].

Infiniband is alive and well in HPC. 327 out of the top 500 machines use it according to this:
