The cluster focuses on debates about single points of failure (SPOF) in systems, questioning if multiple SPOFs are better or worse than one, and emphasizing redundancy and failure modes to improve reliability.

All systems have failure modes; so, use multiple systems to do things that are important.

Are these 'points of failure' ? not single points of failure? I assume some of these have redundancy but could fail.

bagels Feb 16, 2023 View on HN

Yes, but is multiple single points of failure better than one?

brador Apr 27, 2013 View on HN

Wouldn't that mean a single point of failure?

rhizome Feb 6, 2014 View on HN

There's always a single point of failure.

anarcat Jun 5, 2015 View on HN

beats the current system, where there is multiple single points of failures. :p

kitkat_new Oct 4, 2021 View on HN

to also face a failure in the single point of failure - system?

jjn2009 Apr 27, 2016 View on HN

Nope that sounds like the ramifications of having a single point of failure.

sgc Sep 15, 2022 View on HN

I am not familiar with this. What makes them less of a single point of failure?

kristopolous Jan 17, 2017 View on HN

A single point of failure is an advantage?
