 - So this was definitely an attack of some sort... only God knows why
 - I noticed a few new bots that don't use the word "bot" in their user agent and therefore don't match Tomcat's Crawler Session Manager Valve:
   - `Blackboard Safeassign`

+- I added "Unpaywall" to the list of bots in the Tomcat Crawler Session Manager Valve
 - Set up nginx to use TLS and proxy pass to NodeJS on the AReS development server (linode20)
 - Run all system updates on linode20 and reboot it
 - Also, there is 10 to 20% CPU steal on that VM, so I will ask Linode to move it to another host
+- Commit changes to the `resolve-addresses.py` script to add proper CSV output support
