<p>
The status of the stack instance, in terms of its synchronization with its associated stack set.
</p>
<ul>
<li>
<p>
<code>INOPERABLE</code>: A <code>DeleteStackInstances</code> operation has failed and left the stack in an
unstable state. Stacks in this state are excluded from further <code>UpdateStackSet</code> operations. You might
need to perform a <code>DeleteStackInstances</code> operation, with <code>RetainStacks</code> set to
<code>true</code>, to delete the stack instance, and then delete the stack manually. <code>INOPERABLE</code> can
be returned here when the cause is a failed import. If it's due to a failed import, the operation can be retried
once the failures are fixed. To see if this is due to a failed import, call the <a>DescribeStackInstance</a> API
operation, look at the <code>DetailedStatus</code> member returned in the <code>StackInstanceSummary</code>
member.
</p>
</li>
<li>
<p>
<code>OUTDATED</code>: The stack isn't currently up to date with the stack set because:
</p>
<ul>
<li>
<p>
The associated stack failed during a <code>CreateStackSet</code> or <code>UpdateStackSet</code> operation.
</p>
</li>
<li>
<p>
The stack was part of a <code>CreateStackSet</code> or <code>UpdateStackSet</code> operation that failed or was
stopped before the stack was created or updated.
</p>
</li>
</ul>
</li>
<li>
<p>
<code>CURRENT</code>: The stack is currently up to date with the stack set.
