@GeePawHill my LUG webserver at university got slashdotted, hit Reddit, and hacker news at the same time in 2008 or so. Oh, and k5 too, RIP. It was a bog standard off the shelf PC tucked away in an office, running drupal on postgresql. We consumed 99.9% of the university’s traffic and got a nice little visit from IT the next day.
And the machine did indeed slow down a little bit. I mean, if you were looking for it.
I think about that experience a lot these days when people talk about scale.
