Calling all clear
The first step of declaring all clear is making sure that your app does the thing it should. Then you can begin solving the root cause. Note that your first goal is always to bring the system up. Your first goal is not to fix things or to figure out the root cause.
Figure 14: Screenshot of https://status.cloud.google.com/incident/cloud-networking/18004. Notice the two separate messages calling all clear: the first saying things should be becoming healthy, and the second saying that everything is all clear and defining when further communication will happen.
Once you have verified the solution, then post an update saying that things are resolved and mention whether there will be a follow-up. Post at least one more update when you have found and fixed the root cause of the outage. Often this is immediate, but sometimes it takes hours or days to figure out why something happened in your system.
