Abstract: Methods and apparatus for improving performance of a system including a first computing system are disclosed. In one embodiment, the first computing system receives a request via a network from a client device. The first computing system determines whether a second computing system is available to respond to requests from the first system. The first computing system obtains a response to the request received from the client device based, at least in part, on one or more estimated values maintained by the first computing system according to whether the second computing system is available to respond to requests from the first computing system. The first computing system transmits the response to the client device.
