It's impossible for every carrier to connect to every city in their customers’ networks. At the end of the day, not all services are available everywhere.
So what does the geographic coverage of enterprise network services actually look like?
Enter Cloud and WAN Infrastructure, which details the international WAN services, cloud connectivity offerings, and cloud geographies of 180 service providers.
Tracking carrier service expansion required comparing the number of cities in which each carrier offers services across set time periods. New carriers have been added to TeleGeography's Cloud and WAN Infrastructure survey since 2011; a cohort of 151 were present in both 2017 and 2018.
We've maintained data for a core cohort of 49 carriers every year since 2011. Analysis of the five-year compound annual growth rate of enterprise product offerings reflects this group.
Beginning with the 2014 survey, TeleGeography stopped limiting carrier geographic coverage to a set of specific cities, allowing for improved analysis of global footprints. Carriers now report on-net service in 3,926 different cities located in 162 countries. The original list of the top 166 key business centers already capture the most competitive cities.
