As someone who has built and managed multiple websites and platforms on the side, it's a simple fix and I can help a little bit here:

For those unfamiliar with bandwidth:
What is bandwidth?
Website bandwidth refers to the measure of maximum data that can be transferred in a specified time, usually in seconds. That’s why your bandwidth is often expressed as Megabytes or Gigabytes “per second.” The higher the MBPS, the more data is sent and received at the same time. To use another metaphor, if bandwidth is the size of a water pipe, then the data transfer is the amount of water flowing through the pipe. How wide the pipe is, determines how fast the water flows. If you employ higher bandwidth, more data (volume) will be carried. Thus, as mentioned above, bandwidth is simply the data carrying capacity, i.e. the maximum data that can be carried at any given point of time.
