Keurig K-Supreme Smart Coffee Maker Generates Nearly 1 TB of Outbound Traffic in Ten Days
A Keurig K-Supreme Smart coffee maker unexpectedly produced around 1008 GB of outgoing traffic over ten days, overwhelming a home UniFi access point while generating only 9.94 GB of inbound data. The device had been placed on a separate network segment, yet the traffic remained largely internal to the home LAN rather than traversing the internet connection. The anomaly was discovered by user Nomad while assisting family members with network maintenance through the UniFi dashboard. After the coffee maker was powered off, the issue could not be reproduced in subsequent testing, and no packet captures were available to determine the content or root cause of the traffic. The model requires internet connectivity for remote control, scheduling, capsule recognition, and automatic reordering of coffee supplies. No similar incidents have been reported by other users, and the manufacturer has not issued any statement regarding the event.
