The bump in 3Q2021 and the spike in 3Q2024 are both upload of pictures and data to various clouds as I have transitioned my backup strategies.
When the blue stack is below the y-axis that indicates that Comcast didn't report as much WAN data as my router did. The occasional blue is usually an issue with my router collecting data.
Since my 2020 post, Comcast has reinstated their data caps but raised it to 1.2TB. Steady state, I'm still below .5TB. I can throttle my cloud uploads as necessary.
