Abstract: A domain name system (DNS) server. The domain name system server comprises a processor, a memory, and an application stored in the memory. When executed by the processor, the application receives an invalid domain name system address query and, in response to the invalid domain name system address query, returns a query response comprising a loop-back internet protocol address and a time to live value of less than about ten seconds.

Abstract: A self-selected message queue monitoring system is provided. The system comprises a processor, a memory, and an application stored in the memory that, when executed by the processor, presents an interface to a requester enabling self-registration for selection of monitoring of at least one message queue of a plurality of message queues associated with a plurality of user applications. The system also receives a message completing self-registration for monitoring, the message selecting monitoring of a first message queue associated with a first user application. The system also authorizes the requester to access periodically collected information about the first message queue. The system also determines, at a predetermined time, a first metric associated with the first message queue wherein the first metric is specified in the message completing self-registration, and stores the first metric for access by the requester.
