Ask HN: Is there a Slack Bot that will post when AWS / Heroku / etc. goes down?

I want a Slack bot that will pull from the API stream at all of the services that we depend on, and post when it goes down. I find it annoying when, a couple times a year, someone messages me like "hey! your random app you made for fun is down!" and I Google around for a bit and find that AWS is down in Virginia or like Auth0 is down completely, via their status pages.

I am kind of shocked that I can't find an "omni-down detector" that summarizes the outage status of all your dependencies. Does this exist?
