the latter, e.g. I'd assume an competent ISP with a large customer presence on the west coast would have DNS servers for their customers on the west coast, or just use anycast...
- mrsebastian 15y agoYeah, not sure. I think most ISPs use just a couple of DNS servers for their entire network -- or at least that's the case here in the UK. But as you say, anycast might mean that those two IP addresses are actually represented by many servers. I guess we'll need the input of someone who works at an ISP :)
- mcpherrinm 15y ago"A couple DNS servers for their entire network" in the UK is equivalent to having geolocated servers in North America. The UK has a small land area, and so latency talking to the other side of the continent is nowhere near as much an issue.
- davidu 15y agoYou would hope that to be the case, but it is not generally true.
