Hello @peps,
Welcome back!
We re-implemented a Graceful Exit more than a year ago (Graceful Exit Guide (new procedure as of 2023-10-?)), it now doesn’t upload data to other nodes and doesn’t update the status until 30 days would pass. If your node was online with an online score not less than 80% it will succeed otherwise - disqualified.
So, that usage is a usual customers’ usage, maybe there is also a repair traffic, too.
You may check your logs for sure.
