Our public IRC communications network was established back in 1995. What started as a single-server setup has since grown into a proper network, spanning across two continents. 

We operate ~10 UnrealIRCd nodes (3 hubs, located in EU, US and CA). Round-robin hostname (irc.nixnodes.net) DNS responses are based on geolocation lookups against resolver's IP address - the system attempts to direct clients to servers in the same country in order to minimize latency and improve connection stability.
