Contents
- 01
Three definitions of uptime
Connectivity, availability and serviceability — and why quoting the first is why nobody believes the industry.
- 02
Computing a number you can defend
Deriving availability from connector state timelines, handling offline-but-serving, and excluding maintenance correctly.
- 03
The triage ladder
Seven rungs from reading the state to pulling diagnostics, in the order that eliminates the most causes soonest.
- 04
Faults that need special handling
Communication loss, ground faults and missing meter values — why each breaks the standard ladder.
