What
MQTT is pronounced 'mosquito' , ISO20922 describes it.
It's a simple messaging protocol with a publish/subscribe based model.
Where
It seems to run at 10.208.1.49(you shouldnt connect by IP) aka mqtt.vm.nurd.space on the default port of 1883. This is actually running on Jarvis.
We kept the ip and name when we moved the services from Arbiter. But stopped doing so now.
