Process plants are commonly designed to run for 8000 hours/year, allowing time for routine maintenance and upgrades throughout that year.
I'd be quite happy to pitch this to my users if MS would provide a 10% reduction in fees. And serious recompense if they fell below that.
As it stands Microsoft seem to be achieving about 0.93 of a year, or about 1 unit of factory uptime.
As to the name of the El Reg unit, I nominate it "the Tony" after Factory Records founder Tony Wilson.
