We normally watch Stan (Aussie streaming service) on our Nvidia Shield TV. Yesterday evening, as usually, we watched a couple of episodes of our favourite show and then we turned the Nvidia Shield TV off. I work from home so I haven't noticed anything unusual about the device today. My TV was off for the entire day. Around 4 pm I went for a jog and came back home around 5:40 pm. When I walked in I found the TV on - it must have been triggered by the Nvidia Shield TV, but how? The Stan app was on but nothing was playing. Soon after I have received a message from Optus (mobile operator) that I used up 85% of my mobile home broadband internet allowance (we are on a 500 GB Optus 4G home broadband). I was shocked as we normally finish every month at around 350 Gb max. I immediately logged into my Asus router to check what app/device used up all this precious data. The statistics section revealed a whopping 155 GB of data downloaded through the Nvidia Shield TV since 8 pm last night. The app responsible for this huge data usage is called Akamai.net I googled this immediately and I found out that Stan uses Akamai. Therefore I am suspecting that the Stan app has malfunctionedv and somehow it streamed and downloaded over 155 GB within less than 24 hours (roughly 7 GB per hour) despite no movies/shows played. According to Stan's website, streaming UHD equals to roughly 7GB per hour. The thing is we don't even have an UHD TV. Not only I run out of my monthly internet allowance but I am worried if I should continue on using the app on the device or just cancel the service as I would not like this to happen again. Did anyone ever experienced similar?
Akamai is a CDN - which is likely to be the video content traversing their infrastructure. It would appear your Stan app continued to Stream content. If the shield was awake while the TV was in standby, this would explain the data usage
