A non-typical challenge in Web development

An exprience in troubleshooting problems caused by access speed gaps

This is about my exprience as a Web developer in 2014. I call it non-typical because we don't often have to troubleshoot the problems in Web applications constrained by access speed gaps in different countries or continents. It was when I worked remotely for Unetizen last year. We were working on a knowledge-sharing network project. The main target users are in China, Canada and US.
