Hey Simon,

In my previous email, "Healthy Node" and "Failed Node" are two entirely
different servers, completely independent in each other (which explains why
they have different IP addresses).

Sorry - I should have made that clearer! Just wanted to illustrate the
difference in output between a known working server and a failed server.
Your thought process did spark my interest in DHCP logs; however, the IP
address has been consistent throughout the issues.

Thanks,
Zach
