Ask Slashdot: Unattended Maintenance Windows?
exactly. it doesn't really matter if you are there or not. eventually something is going to break in a new and interesting way that can't be fixed without a significant amount of work.
generally we try to have at least three systems for any production service so that we can still have redundancy while doing maintenance.
that said, I rarely come in for patching anymore. I just make sure I'm available in case something doesn't come up afterwards. (no binge drinking on patch nights!)
redundancy and proper monitoring make life much, much nicer.
Telnet into Dreamcast?
Actually I have seen the term, SoftModem being used by modem manufacterers. *I guess they don't like windows either* ;)
