However, I notice from Atlas that from January 1st, the exit probability of my server dropped dramatically and has stayed that way together with the observed bandwidth being always a small fraction of the speed I advertise:

So I'm curious as to whether there's anything I can do to bring my consensus weight up, apart from just ensuring continuous uptime. That's not often under my control though, since reboots for kernel updates etc. come quite regularly.

Apologies if this a common question, but some initial searches on the subject turned up rather too much information for me to understand!
