Interesting. Just a few weeks back, I was reading about their previous work https://atscaleconference.com/the-evolution-of-aiops-at-meta... -- didn't realise there's more work!
Also, some more researches in the similar space by other enterprises:
Microsoft: https://yinfangchen.github.io/assets/pdf/rcacopilot_paper.pd...
Salesforce: https://blog.salesforceairesearch.com/pyrca/
Personal plug: I'm building a self-service AIOps platform for engineering teams (somewhat similar to this work by Meta). If you're looking to read more about it, visit -- https://docs.drdroid.io/docs/doctor-droid-aiops-platform
