The second law of thermodynamics guarantees that there will always / eventually be downtime… and that’s okay. Design for downtime. Shameless self-plug for https://heiioncall.com/ for free website / HTTP endpoint monitoring and cron job monitoring if you want to know about your own app’s downtime. EDIT: thanks to those of you who have signed up in the past few minutes! Let us know if you have any feedback.
"eventually" is doing a lot of work in that sentence. Our sun will last another 5 billion years, and the heat death is something like 100 trillion years away.
Though a lot of practical thermal-related causes of electronics failure seem to operate on timescales of years to decades, like electromigration https://en.m.wikipedia.org/wiki/Electromigration or even just cooling fan bearing failure. And I don’t think it would be a huge stretch to point to electromigration as a case of diffusion, a natural entropy increasing process, re-randomizing the arrangement of atoms within a transistor (and therefore making it fail eventually).
