Microsoft Azure geo-redundant storage (GRS) is not instantaneous, so they expose a "last sync time" value to help users/admins understand the lag in geographic replication. Unfortunately the docs do not give any indication of how much lag is typical, so as a new user of Azure it's hard to know what to expect. Is it typically seconds, minutes, hours?
Clearly the ideal answer would be to perform some empirical tests, but for people who have already been using it, what type of lag do you typically see?
