Where 1883 fits
Why 1883 is special
MQTT was built for links that are slow, expensive and unreliable — originally oil pipeline telemetry over satellite — which is exactly why it suits home sensors and industrial equipment. Port 1883 is the unencrypted form, and internet-wide scans routinely find open brokers publishing live data from homes and factories.

- Science
Krakatoa's 1883 eruption was audible in Australia and Mauritius and registered on barographs worldwide. Because the telegraph network already existed, it was also the first disaster reported globally within hours.
- Technology & computing
MQTT was designed for satellite links monitoring oil pipelines and turned out to suit anything with a poor connection and small messages, which is most of the internet of things. Port 1883 carries it unencrypted, and internet-wide scans routinely find brokers publishing live household and industrial data.
