Hello @lovaszl
More than the change of pricing for the test satellite, what is affecting you (and all storage node operators) is a decrease of traffic this month, maybe related to the policy in terms of free account and ban of some free accounts to limit abuse.
Anyway as I said, all nodes operator are seeing more or less a decrease by 20-30% of the estimated payment for this month and noticed a decrease of egress and ingress, so your node should be perfectly fine.
