Abstract

In some examples, a system for managing distributed data can include a processor to detect an update notification from a client device to update a managing server, the update notification indicating that a remote server node is unavailable. The processor can also generate a comparison value by comparing a first time stamp to a second time stamp, wherein the first time stamp corresponds to a time at which the system receives the update notification from the client device and the second time stamp corresponds to a time the remote server node transmits a set of renewal data. Furthermore, the processor can determine that the comparison value indicates the remote server node is unavailable and remove the remote server node from the managing server.
