Looks like eXtremal may have closed the Datacoin pool.

Still down and no response to my post on the above thread.https://bitcointalksearch.org/topic/m.56535610
Network hash rate has crashed somewhat which is a shame but ...
As sampei7777 observes, the dtc.graymines.net pool is still mining. Go to https://dtc.graymines.net/index.php?id=start for downloadable Windows binaries of the GPU xpmclient poolminer.

I have the latest Linux xpmclient-cuda-10.3-linux binary for nVidia GPUs (courtesy of eXtremal's coinsforall.io) which I've got pointed at dtc.graymines.net and is happily running on my old Dell XPS 9560 laptop's built-in GeForce 1050. (I needed to heed its instructions to use xpmclientnv -c to adjust it to handle graymines' use of the older protocol.
