Linux Spheres of Support for Dedicated and Managed Operations

This article outlines our support of software and server configurations for machines (virtual and physical) running a supported Linux® operating system.

Operating systems

Operating Systems and Platform support Matrix:

📘

Rackspace makes every effort to align our support dates for operating systems with the manufacturer's support dates. If a manufacturer decides to shorten the support life of an operating system, Rackspace might be forced to end support sooner than originally anticipated. For full details on support life, see the Rackspace EOL Terms.
