This is not some AI failure, nor the fault of some hapless manager.

This was a failure to recognize the potential for cascading error handling.

It's DNS, for sure. If i had a dime for every hour of DNS-related outage i ould be living a whole different life.

The issue is not that bad DNS data got pushed out. That is a recoverable situation.

The issue is that other automated tools were unable to recognize that reversion was actually recovery.

Anyway, good luck with vibe-coding
