It depends on what the provider does as part of its server management. Many hosting providers consider themselves managed hosting providers because they maintain the hardware of the server, the operating system installation, and ensure the server has power, cooling, and network connectivity. Others offer a limited amount of support for you but would not help you, for instance, during a disaster, a migration, a hack, an issue with website, DNS or email configuration, etc. You would have to ask your provider what their management entails and what SLA you have with them. Some customers left us when moving to a managed provider only to return, saying the server management service is not the same as our Server Management Service. You would have to ask the provider what their management entails.
