random guess: the servers are reached via anycast. if you DDoS from the US, you'll take down access from the US, but not from other regions.

It's not much of a DDoS if it's from a single country.

That’s pretty invalid — I often see large attacks that are almost entirely made up of bots from one country.

Isn’t the point of anycast to absorb the brunt of the attack? If your traffic is localized, maybe dropping the announcement for that PoP would be useful.
