I'm curious about how regular hardware maintenance improves reliability. Are you just cleaning out dust? Or do you do periodic stress tests to catch failures early?
regular maintenance helps with reliability because we do a lot of work proactively with power, hvac, switches, etc. which reduces likelihood of failure. Being able to perform maintenance in general is generally good for the stability of our system.

HW does fail over time and needs to be replaced. This involves shutdown of physical infrastructure at different levels.
