It’s funny to me as a physician to see “you’re not a hospital” as an example of a system that cannot tolerate downtime. Epic, probably the biggest EHR provider in the US, has planned downtime for upgrades at least monthly, for 30-60 min each.
We had three windows at 1 am where any new critical patients would be diverted to a different hospital. The first we used for major maintenance to the breakers in the switchgear, the second we used for modifications to the bus work, and the last outage was to test the operation of the new control system.
They do a transfer to diesel every month and the whole hospital is aware of it in case it results in a blackout.
Doesn’t epic cover everything from patient admission to medical imaging?
If anything, the hospitals are much more reasonable in terms of expectations of uptime than people's expectations of cat video avaliability.
We used to get 4 hour downtime windows to completely redo switch stacks for every switch closet in a location over a single week for example.
