My HTTP server sits in Czech and uses Cloudflare’s free plan.
I can visit my server from Taiwan and experience fairly fast response speed. A friend of mine also reported short home page delivery time using a mobile phone from an airport in Cambodia about 3 days ago.
However, recently two Chinese visitors (one of them was in Dalian, north east of China) responded that my web pages were so slowly delivered that my server was nearly unreachable.
Any idea about boosting the slow transmission speed in China will be greatly appreciated!
