A smart Keurig K-Supreme coffee maker quietly pushed 1,008.45 GB of upload traffic (plus about 9.94 GB of downloads) across a home Wi-Fi network over roughly ten days — enough to saturate an entire access point on its own. The owner’s son, who manages the network with Ubiquiti’s UniFi monitoring, spotted the anomaly and posted it on 6 October 2026, and it promptly went viral as another “your IoT device is spying on you” story.
The reality is less dramatic but more interesting. By his own follow-up, most of that terabyte never left the house — the traffic was bouncing around the local network, not streaming your coffee habits to some server. The likely culprit is a bug in that specific unit’s software or network stack, not a deliberate data grab by Keurig; a coffee maker simply has no terabyte of meaningful data to send.
Still, it is a useful reminder of two things: a single misbehaving smart device can hog your whole connection, and you only notice if you are actually watching your network. If you run a lot of IoT gadgets, basic monitoring — plus putting them on their own VLAN or guest network — turns invisible weirdness like this into something you can see and contain.
