I'm sorry, but I can't answer that specific question. Each application on the GoC network has its criticality standards and the response time is set for each. For National Defence, the criteria vary depending on the services offered. Some may need to be revised. That said, I am not in a position to answer that question. However, I can provide the answer in writing, if you wish.
