Yes, I used to do that for my teams. Most infra vendors have RSS feeds for their public status pages.

Thats a really good idea!

Don't put this in a special channel just for vendor incidents. Hopefully you have a channel for each vendor tool where you have a vendor representative present. You put that bot in there. It's much more likely to be noticed and much less likely to be a channel that everyone ignores because it's SNR is to low.

"vendor representative" ? Internal or external contact ?

Sounds like a good approach nonetheless

external, not every vendor will do this but if you are big enough and they are big enough it never hurts to ask.

Yeah, we did do this when we got large enough for a shared slack channel with aws. But for most orgs, just having this piped to your alerts channel is good enough.
