(Google Customer, not Employee)

We have two slack channels here. One is where our internal monitoring agents post, as well as an RSS subscription to the GCP status board. We have a separate channel for less critical things (like GitHub).

Unfortunately, it does depend on GCP updating their dashboard. However, to date, we’ve only been impacted by one of these major outages. This morning, I saw the alert in our channel, but all our things were still operating (fortunately!).

YMMV, but I’ve found this very helpful.

FWIW, we're exploring ways to make this better. We know it's a point of pain for customers. One of the challenges is that the "project owner" isn't always the right person to receive these kinds of alerts, since often that's someone in the finance department or central IT team. There are a few ideas being thrown around about more proactive notification right now.
