We have periodic code updates on our drupal based back end. The back-end servers have a maintenance mode that will return a 503 for HTTP requests without cookies.
The code updates sometimes take several hours - enough for the cached copy to expire. Grace mode appears (sorry; single data point; this is what the developers told me) to time out after an hour no matter what we set it to in vcl_recv/vcl_fetch. Is there a better approach to have everything that's cacheable available for a few hours? What are others doing? TIA, --- David
