Intermittent stale cached responses on gablvm.org

During three brief windows overnight, visitors to gablvm.org may have received a stale cached response from our content delivery layer instead of the requested page. Each window lasted about ten minutes or less and cleared automatically, and most visitors were unaffected. A fault in our automated cache recovery process was identified and corrected the same morning.
