For comparison... When that site went up, about 8 days in, I believe, they said they had used 550+ gb of bandwidth and it seems like it was about $45 in costs at that time... Today, if they just used $40 of bandwidth in 2 hours, well does not take a rocket scientist to figure that one out.
So does that mean if I leave my webpage displaying that site when I leave the house, I continue to use bandwidth even though I’m not looking at it? Maybe that’s what’s happening - people are “monitoring it” in case new drops show up?
