The Wikimedia Foundation operates a network made of 2 main datacenters (Ashburn, Dallas), 3 caching sites (San Francisco, Amsterdam, Singapore) and 3 networking sites (Dallas, Chicago, Amsterdam).
Since 2017, this network is unified under AS14907.
Those sites are connected in a redundant way to each other using dedicated fibers, wavelengths and VPLS circuits.
Connectivity to the world is achieved via various transit providers and exchange points.
