Data retrieval time

When a user tries to replay an interaction archived in Glacier, the time to retrieve the data depends on the tier associated with the account.

With expedited retrieval, the replay can start in seconds. However, If the time to retrieve the data exceeds the 30-second timeout, the user is prompted to try again.

With the slower restore options (Standard, Bulk), the user receives a message, "Media not available - retry in a few minutes," even though the retrieval can take up to several hours.
