Similar in Greek academic networks, adapting to local mythology. The amount of routers and mail servers named 'Hermes' was ridiculous.

Different experience in English academia, where I encountered random names (e.g. 'mira' for a shell server and 'laplace' for a Physics Dept server). The acronyms could at times be interesting. Particular favourite was a 'central university network time' server. That was later renamed to ntp.*.ac.uk, after stern recommendations.

Around 2000 I was working at the small bank that had servers named by currency. Development server happened to be "dong". Eudora had some spicy language detection and used to show me some red chili peppers every time I'd mention that server in email.

In Colorado, USA, all 5 companies I've been inside conference rooms of use specific mountains (or ski towns) in the area. I've been in meetings in Longs Peak in 3 different companies.

Same experience in Norway and Sweden. Followed very closely by sci-fi/fantasy characters or authors.
