I guess on a load balancer or DNS level? A request has to hit a single domain name / IP before it's load balanced to the distributed system right?

Multiple devices in very different parts of the world can respond to the same IP address. A great example are DNS servers like 1.1.1.1 and 8.8.8.8- you get routed to the nearest site that can handle your request. A common example of how this is implemented is via anycast: https://www.cloudflare.com/learning/cdn/glossary/anycast-net...
