Hello @eekthecat,
Welcome to the forum!
The usage depends on the customers, not a hardware, so any behavior is normal, just make sure it’s online and has free space (otherwise it would serve only egress, i.e. downloads by the customers or repair/audit workers).
Satellites also have cache, if your node was detected as offline, they likely removed it from their cache and your node become a usual (not “hot”) node - the node selection is random by its nature.
The other fact which could affect the node selection is your node vetted or not.
Each new node must be vetted, while unvetted it can receive only 5% of the customers uploads (will be changed to 1% soon) until got vetted. To be vetted on one satellite the node should pass 100 audits from it. For the one node in the same /24 subnet of public IPs it should take at least a month (if more than one such node it could be longer).
