Methods, systems, and computer-readable media are provided for updating a search index with new uniform resource locators (URLs) and spiking URLs with increased user interest. History data, provided from browser applications residing on users' computers that indicate URLs accessed by the users, is parsed to identify new/previously unknown URLs. The history data also indicates URLs in which there is increased interest based on a number of recent hits as compared to an average number of hits determined over time. Author postings of new URLs to social networking sites and a quality rating of the authors may also be used to identify and filter new URLs. Search indexes are updated with the new and spiking URL data. As such, lag time between posting of new URLs and spiking of URL interest and inclusion of this data in a search index is greatly decreased.

Embodiments are directed to promptly reestablishing communication between nodes in a dynamic computer network and dynamically maintaining an address list in an unstable network. A computer system sends a message to other message queuing nodes in a network, where each node in the message queuing network includes a corresponding persistent unique global identifier. The computer system maintains a list of unique global identifiers and the current network addresses of those network nodes from which the message queuing node has received a message or to which the message queuing node has sent a message. The computer system goes offline for a period of time and upon coming back online, sends an announcement message to each node maintained in the list indicating that the message queuing node is ready for communication in the message queuing network, where each message includes the destination node's globally unique identifier and the node's current network address.
