A comment on 2,500 continuous runtime hours on a 4.77Mhz DOS web server.

The complexity of operation of 2500 hours at 4.77Mhz, single core, is equivalent to about an hour on a garden variety modern server.

In my mind, this stuff is impossibly reliable and should simply not work, but here we are.

Are you referring to the CPU used for the site? If so, how did you arrive at one hour? I'd put it closer to a second.

I was being extremely generous, but you are closer to the reality of the situation.

Back of the napkin-

assuming 2020 tech, 20 cores, 2.4ghz and ignoring all of the non-cpu complexity growth, it would be around 0.2 seconds lol.

If you were to wrap in the actual system complexity *operating frequency we’d probably be around 10ms equivalent complexity.

The reliability of modern computing systems is ridiculous.
