A short video of five people carrying a live, running web server across the city by public transport to a new datacenter. It stayed powered and connected to the internet the whole way, so there was no downtime.

HN treats it as the classic example of moving a live server with zero downtime, brought up whenever the topic of uninterrupted migration comes up.

From a few years ago: > Five guys moving a server to a new datacenter without shutting it down. Without cutting it off from the internet. And as using a car would have been too easy, they used public transport. * ▶ this video (DE audio, EN subs)

These sysadmins moved a webserver across their city while keeping it powered and connected to the Internet... ▶ this video

A real classic comes to mind: ▶ this video Moving a running server about 7km through public transport without downtime.

Oh for sure this is possible: ▶ this video the devices that do it without doing what these guys did is quite pricey though link
