I've been doing this for 25 years and I'm not sure what this means. Dell isn't going to come back to you and say "sorry but we can't fix this". With the warranty SLA worst case scenario they'll just replace the entire machine if they have to although I don't remember ever seeing it come to that.
> just plain "Actually, THAT failure mode isn't redundant."
When it comes down to it similar issues exist with clouds - regions, availability zones, etc. Big clouds have had multiple widespread outages just this year[0].
From that reference you can see that MS and Amazon themselves struggle to design, build, and run solutions for their own products in their own clouds.
It's always interesting to see marquee household name companies/products/solutions go down when US-East (or whatever) is having a bad day again.
Cloud can be a lot of things but a silver bullet for reliability and uptime isn't one of them.
