Useful, but a bit spotty in details. I think it assumes that I
already know a lot more about Cyrus. I don't have a sand-box lab to
test it so my level of confidence is very low.
Add to that the tiny matter of most of the back-end machines being
deployed more than 3000 km away...

SASL is mentioned.

OF course. But the geek who made the changes at least figured out
that it was a naming problem he created when changing the order of
name resolution after I asked him about the "few changes" he'd made
after I left the system running.

Erm no. ISC DHCP first pings the address before handing it out.
The extra delay is a worthwhile sacrifice compared to breaking a
network connection to an existing host; which with Windows can
easily result in file corruption.
