Abstract: Systems and methods are provided for highly accurate synchronization of machine instances in a distributed, hosted computing environment to a reference timekeeper. In addition to a general communication network accessible to machine instances, the distributed environment includes a second network dedicated to carrying time information, such as a pulse-per-second (PPS) signal to isolated timing hardware within host computing devices. The isolated timing hardware can use the PPS signal, along with a reference time, to set a hardware clock. The isolated timing hardware can further provide an interface to machine instances that enables the instances to read the time of the hardware clock. This configuration enables many instances can share access to a single reference timekeeper, thus synchronizing those instances to a much higher accuracy than in traditional network-based time protocols.

Abstract: A cage assembly may define a part of a computing appliance. The assembly can include a cage formed by walls and defining a continuous interior volume bounded by a top face, a bottom face, a right face, a left face, a front face, and a rear face. A first edge connector may be within a leftward portion of the interior volume. A second edge connector may be within a rightward portion of the interior volume and positioned laterally from the first edge connector. The arrangement may permit engagement with multiple individual-width plugs (e.g., each bearing an individual paddle card) or a single plug (e.g., bearing multiple paddle cards spaced laterally from one another and aligned for engagement with the first and second edge connectors within the cage).
