(find nodes in zmq_list.txt)
active here: https://xmrvsbeast.com/p2pool/monero_nodes.html

If you don't have a local node yet, you can 'bootstrap' from a remote node in the list.
pulls zmq nodes from monero.fail on the hour / every hour. In the monero gui just go to Settings -> Advanced -> p2poo mini -> Add --host the.ip.address to start up flags (where 'the.ip.address' is the node e.g. node.sethforprivacy.com

for nodes who have non standard ports ( 18081 for rpc and 18083 for zmq ) you add these options after --host:

--host example-node.com --rpc-port 18089 --zmq-port 18084
