I'm wondering why this relay is almost unused: Fingerprint 605EE4375EE4C38215C8949F5808863749FD4F4A ?

It's running on a 1 Gbit link and there is plenty of unused bandwidth. The bandwidth is set to 42 Mbps (even prioritized on the internet link). There were no outages for months and the connection is stable and fast. There's also plenty of resources available on the actual router (tor instance).

Relay monitoring shows usage average around 0.5 - 1 Mbps only (so around 1-2 percent of the available bandwidth). Consensus Weight is down to only 99. Any idea what could be the reason of the low usage, low Consensus Weight ?
