Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving a plurality of requests from a plurality of client devices sent to a public internet protocol address; routing the requests to one or more internal Internet protocol addresses, where the one or more internal Internet protocol addresses correspond to one or more compute nodes, and where the one or more compute nodes process the routed requests; determining a particular compute node is offline, where the particular compute node is assigned one or more internal Internet protocol addresses; in response to the determination that the particular node is offline, reassigning the one or more internal Internet protocol addresses corresponding to the particular compute node to one or more different compute nodes, where requests communicated to the reassigned internal Internet protocol addresses are communicated to the one or more different compute nodes for processing.
