  2. Overview • Discussion about the usage of LoST Sync revealed different deployment approaches for LoST. • Short summary of the deployment choices and the implication for LoST Sync. • Walking through an example of • Austria with 1 FG, 3 LoST servers and many PSAPs • Finland with 1 FG (with co-located LoST server) and several PSAPs hidden behind an ESRP.
