Techniques are disclosed for validating the resiliency of a networked application made available using a distributed computing infrastructure. In one embodiment, a latency monitoring application observes each active application component and at specified or unspecified intervals, selects one and introduces latency or error messages in one or more messages emanating from the selected active application component. The latency monitoring application then measures the effect of the latency or error messages on other active application components that are dependent on the affected active application component. By observing the effects of the failed server on the rest of the network application, a provider can ensure that each component can tolerate any unexpected latency or error conditions with the distributed computing infrastructure.

A device, system, and method are directed towards determining network information. A network address is determined for a possible proxy. A determination is made whether a port on the possible proxy is open and/or if the port supports an HyperText Transfer Protocol (HTTP) proxy request. A request is sent to the possible proxy over the port, the request being configured to be forwarded to a network device. A type of the possible proxy is determined based in part on a behavior of the network device. The behavior may indicate whether the request is received by the network device, or whether the possible proxy obscures an origin of the request. The proxy type may include whether the possible proxy is a non-proxy, an anonymous-proxy, a controlled-proxy, and/or an open-proxy. Various types of network analysis may then be performed using the possible proxy and the determined proxy type.
