For some reason, Cloudflare uses a block of IPv6 addresses from APNIC,
even though they are in California. When I do a traceroute from my
cable modem in New York, it is two hops past an he.net router in New
York City and pings in about 40ms which tells me that the addresses
may be from Hong Kong but the servers are in San Francisco.
