Node in eu, no traffic from eu satellite... why?

The customers could be around the globe, not necessarily from Europe.
You can just check, how many nodes in Europe:, so it’s quite possible that your node is slower than many of these nodes…

This is due the missing reports from the US1 and SLC satellites:

So, this is just incorrect data, thus - incorrect assumption of the unpaid data (the script compares the reported by the satellites used space with the node’s used space and assumes that this is an uncollected garbage).
