Last month we've got Droplet Bandwidth Overage (2825.36GB @ $0.01/GB) = $28.25 extra charge for exceeding the current summary limit of 8429 GB per month.
It doesn't seem so clear from the invoice which droplet's overage caused this extra charge.
vnstat instances running on regular droplets don't show something unusual.
Kubernetes cluster services logs don't show something extra ordinal as well.
Please, can someone clarify the situation with bandwidth overage?
