A Keurig K-Supreme SMART coffee maker generated roughly 1TB of Wi-Fi traffic over just ten days, severely slowing a US user's internet connection. The device was collecting and transmitting data about its operational status, brewing progress, capsule recognition, and software version.
Most of the traffic stayed within the local network rather than leaving the home, suggesting the machine was uploading data to a local server or performing repeated synchronization tasks. The cause appears to be a malfunction specific to the device, though the exact trigger remains unclear. Keurig has not yet provided a public statement about the issue or whether other K-Supreme SMART units are affected.
This coffee maker is not sold in Brazil. The incident highlights how everyday connected devices can unexpectedly consume massive bandwidth when software bugs occur, turning what should be a convenience feature into a network performance problem.
