The WMTS tiles are served from multiple subdomains, as listed in the GetCapabilities document. This allows web clients to work around a limitation in browsers, which limit the number of concurrent connections to a single domain to some small number. By serving tiles on multiple domains, the web client can speedily fetch a full screen of tiles without hitting the browsers limit on concurrent requests. Non-web based clients without this limitation can request tiles from a single domain, or all domains, as they choose.
