View the block public access setting for Amazon EBS snapshots

Block public access can be in one of the following states for each Region in your account.

  • Block all sharing — All public sharing of your snapshots is blocked. Users in the account can't request new public sharing. Additionally, snapshots that were already publicly shared are treated as private and are not publicly available.

  • Block new sharing — Only new public sharing of your snapshots is blocked. Users in the account can't request new public sharing. However, snapshots that were already publicly shared, remain publicly available.

  • Unblocked — Public sharing is not blocked. Users can publicly share snapshots.
