EMS metrics use metrics from both strings. Lalit confirmed they take the minimum latency of the two, NRT 1 and NRT 2.
CMR currently takes granule metadata from the primary server NRT1.
Dana Shum and Doug Newman commented on whether the ECHO and CMR could handle the additional 'duplicate' granules. Doug confirmed they could ingest the additional volume of granules but they questioned if this duplicate is 'the same' data then it might cause confusion to the user.
