Honestly, I don't think we're entitled to a deep technical write-up. We are users of their product, they messed something up, and that's it. Unless they signed an SLA agreement, it's just shit that happens. They don't have to give a technical view into their internal kitchen if they don't want to.
The biggest problem is that if you're using this in production then it could cause problems. It's not like a traditional outage where you get a load of 503 errors, the system appears to be working correctly but generates gibberish. If you're using this in a chat bot you could be liable for things it's saying...
