Thats a really big "depends"
Are they running VMS?
Are they running a UNIX?
How many people still know VMS?
Do they have a competent sysadmin or hardware guy?
Did they outsource their IT to an incompetent supplier?
When the machine went down did the power supply blow when it came back up?
Did this set off the fire suppressant system?
Did this cause other machines to power cycle and also blow?
