WordPress.com is a managed platform for building and hosting websites, blogs and newsletters on WordPress. It offers hosting, themes and patterns, a drag-and-drop editor, domain registration, online stores and professional email, plus developer tools such as a REST API. It is aimed at individuals and creators, small businesses, and developers and agencies; WordPress VIP serves large organisations. WordPress.com is delivered as software as a service and is operated by Automattic.
Automattic is a privately held US company headquartered in San Francisco, so US legislation such as the CLOUD Act can apply. WordPress.com runs on a modified version of the open-source WordPress software, which can also be downloaded from WordPress.org and self-hosted; the hosted service itself belongs to Automattic. Customers can choose a primary data center: US West, US Central, US East or EU West. This is possible only when hosting features are first activated, and the choice cannot be changed afterwards. If a problem occurs, the service fails over automatically to a second data center.
