    Abstract: Technologies are provided for active monitoring of network fabrics, such as border network fabrics. For example, test packets can be generated and sent to destination devices within the network fabrics. The test packets can have destination ports that have been identified as closed destination ports. The success of the test packets can be determined based on whether ICMP error packet responses are received. If a network problem is detected based on results of the test packets, then traceroute packets can be used to identify the location of the network problem.

    Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces on those devices. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases for simplicity, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

    Abstract: Techniques described and suggested herein include systems and methods for identifying potential sources of infections of devices by unauthorized code. In an embodiment, network traffic is logged. A plurality of computing devices that include unauthorized code is identified. The logged traffic is used to identify information sources accessed by the identified affected devices. The identified information sources may be refined. Refinement of the identified information sources may include excluding information sources that have been accessed by uninfected devices. A user interface that allows a user to further refine the identified information sources may be provided.
