This website (referring to guozeyu.com, the same below) WordPress blog using Aliyun Hong Kong server with BGP network.
Overseas data center also have Google US-Central, OVH France, QuadraNet US-West in addition to Aliyun Hong Kong. The static HTML generated by the entire WordPress site will be proactively pushed to these servers. For unbuffered content, the best line back source is chosen. Europe to Beijing to go directly to China Telecom, delayed about 180ms; Europe to Hong Kong Hurricane Electric, delayed about 180ms; the western United States to Hong Kong PCCW Global, delayed about 150ms; Central America to Hong Kong to go Google FASTER, delayed about 160ms.
Most of my domain names now use self-built DNS, support DNSSEC, GeoIP, and IPv6. For DNS servers, Asia Pacific subscribers assigned Aliyun Hong Kong, Aliyun Beijing, and Google Singapore servers, while overseas users assigned Google US-West, Google US-Central and OVH France servers.
Now the site has full support for IPv6, the use of CloudFlare CDN also supports the acceleration of IPv6.
