The connection is up-and-running perfectly fine without any issues or interruptions for at least a month.

On Relay Search, the Advertised Bandwidth is made up of 3 different bandwidths.

For your relay, they are:
Bandwidth rate: 3 MiB/s
Bandwidth burst: 6 MiB/s
Observed bandwidth: 1.3 MiB/s

You can see these details by clicking on the Advertised Bandwidths figure on:
https://metrics.torproject.org/rs.html#details/605EE4375EE4C38215C8949F5808863749FD4F4A

The observed bandwidth is the maximum bandwidth peak your relay has seen. It's updated each day.

Tor is a low latency network, so it's normal for relays to be loaded at 10-50% of their capacity. (Congestion increases latency.)

If you'd like your relay to get more traffic, please increase your RelayBandwidthRate and RelayBandwidthBurst.
