These are the current (and former) server clusters used by the Wikimedia Foundation, grouped by colocation facilities. Cluster names are formed form a two-letter abbreviation of the hosting provider (e.g. "eq" for Equinix) and the three-letter IATA code of the nearest major airport (e.g. "iad" for Washington Dulles).
