Memex Login Hung on 11/17/21

Initial incident and probable cause:

Broken pipe on the login caused by a file update on the login. The master node and login were both rebooted and “wwsh file sync” commands were automated memex_routecheck.sh (crontab and cron.hourly). After reboot, the routing table and maintenance motd were both updated sooner than before. Also added a ping check in order to determine whether the networks needs restarting (after the routing table is updated).
