" summary

WorldwidePageTest.com tests a URL from many real locations and plots latency and waterfall results on a world map, using the WebPageTest API to enumerate locations and run Chrome jobs, and ASP.NET with SignalR for real‑time map updates and Dapper for DB access. The demo shows filtering by region and browser, produces top‑10 average graphs and raw data feeds for import back into WebPageTest, and is a Microsoft ASP.NET app that failed live but runs offline.
