\begin{abstract}

A basic task in distributed computation is the maintenance at each
  processor of the network, of a current and accurate copy of a common
  database. A primary example is the maintenance, for routing and
  other purposes, of a record of the current topology of the
  system. \par Such a database must be updated in the wake of locally
  generated changes to its contents. Due to previous disconnections of
  parts of the network, a maintenance protocol may need to update
  processors holding widely varying versions of the database. \par We
  provide a deterministic protocol for this problem, with only
  polylogarithmic overhead in both time and communication
  complexities. Previous deterministic solutions required polynomial
  overhead in at least one of these measures.
