So, we used to have an incredibly obnoxious and cumbersome naming scheme, where the first letter was either S for system or N for network, then a four-digit location code, which started with 1 for East Coast and Europe and 2 for West Coast and Asia-Pacific. Then a 3-letter code that gave a vague hint regarding the machine's function or model, then a 2-digit serial number. Thus, s2009mgw06 is the sixth mail gateway machine at location 2009 (our current colo).
The new and improved naming scheme is: one letter, P for production, D for development, Q for QA; a two-digit location code; a mandatory 3-letter, "vague hint" code; an optional 3-letter supplementary code; and a 2-digit serial number. Thus, p01dnsi03 is the third 'i'nternal DNS server at location 01 (the new colo).
Someone explain to me how the latter is an improvement. I really, really loathe this.
