Methods, systems, and apparatus, including medium-encoded computer program products, for decreasing latency perceived by a user in retrieving data from a data server. A user-initiated interaction with a user interface can be detected and a user-generated request to retrieve data automatically predicted, based at least in part on the user-initiated interaction. Resolution of a domain name into a network address can be initiated, based on the predicted user-generated request to retrieve data, prior to receiving a user-initiated submission of the user-generated request to retrieve data. In certain instances, a network communication synchronization sequence with a data server associated with the predicted user-generated request to retrieve data can be initiated prior to receiving a user-initiated submission of the user-generated request to retrieve data.
