A distributed computing system used for controlling a telecommunications network includes a number of computers interconnected by a data communications network each computer storing a plurality of data records. The computers are programmed to access records held on other computers and are programmed to move the record to another computer. Each computer is further arranged to store a table of data indicating the computer on which that record may currently be stored, and to update that table when the record is moved. Each computer is further programmed to store a log of the identities of the other computers which have accessed the record, and the computers are further programmed so that after moving the record, the computer sends a location updating message to at least one further computer determined in accordance with the log.
