This server runs Zcash mainnet and testnet nodes. Our server is dual-stack (IPv4+IPv6) and available over Tor as well:

v3: dankdoggo6aq2amfesdg6vin742ciiuapaoow2z3wnxzctjuazjjb5qd.onion

We also have HTTPS+BitTorrent+HTTP-over-Tor mirrors of Zcash MPC ceremony transcripts: see /transcripts/ directory and README.txt there for more!

Finally, if you want to compare notes with a well-connected node like ours, /rpc/ contains output of various zcashd RPCs. These are updated every 30 seconds.
