A blogger recently wrote an article “The 4 Best Web Hosts For Nigeria Websites (& 4 To Avoid)” detailing how hosts making use of servers based in the USA are better for residents of Nigeria. His test was based mainly on latency of the web hosts website.
The site speed testing service has no single server on the African continent. A test from within Nigeria would have been way more accurate. Why should Web4Africa be blackmailed with speed tests to Singapore, Sydney, Japan etc when about 80% of our valued clients are in Africa?
In Nigeria, we deliver a latency of 1ms to most local ISPs, at very high speeds. That surely trumps the 200ms+ latency and low speeds from the USA to Nigeria.
For a website that is chasing a global audience, Content Delivery Networks (CDNs) exist to breach the global latency issue. Thus, the location of your hosting server would not matter much if you make use of a CDN service that has a really global footprint.
A content delivery network or content distribution network (CDN) is a geographically distributed network of proxy servers and their data centers. The goal is to distribute service spatially relative to end-users to provide high availability and high performance. CDNs serve a large fraction of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social networks.
Say your website is hosted in Nigeria, the speed to users in far-flung places like New Zealand, Canada, Argentina, Russia etc would be very fast if the CDN service has a server presence in those locations. Example of global, large-scale CDN services are CloudFlare, Fastly etc.
