Hey, I'm the tech lead of Workers. I don't want to intrude too much on this thread, but just wanted to say: we don't do any special load-balancing for Workers requests; they are treated the same as any other Cloudflare request. We use Anycast routing (where all our datacenters advertise the same IP addresses), which has a lot of benefits, but occasionally produces weird routes. Often this relates to specific ISPs having unusual routing logic that, for whatever reason, doesn't choose the shortest route. We put a lot of effort into tracking these down and fixing them (if the ISP is willing to cooperate). We do sometimes re-route a fraction of traffic away from an overloaded datacenter by having it stop advertising some IPs, but if the internet is working as it should, that traffic should end up going to the next-closest datacenter, not around the world. When you see requests going around the world, feel free to file a support request and tell us about your ISP so we can try to track down the problem and fix it.
