Several large usage spikes
I was looking at my internet usage details and one Sunday this month, 150 GB of braodband was used from midnight to 1 am. There was no one in the house at that time. This afternoon, 20 GB of broadband was used between 4 pm and 5 pm. We were home, but neither of us was using any devices. This is way out of line from any other time. Any suggestions or recommendations? Thank You.
