StrorageGRID 11.5 or later

Answer

Data loss might occur.
Assume the following scenario occurs during the networking down:
-User A via site A  edited object X as object X' at Timestamp 1
-User B via site B  edited object X as object X'' at Timestamp 2
-Timestamp 1 is earlier than Timestamp 2
 
After the network communication between sites is recovered and client requests GET object for object X, then StorgeGrid will drop object X' and only return object X'' to client because StorgeGrid compares the timestamps and always picks up the latest one as a GET response.
