A few weeks ago, I submitted an incident with sample code and got a response back with code to implement a workaround, and the information related to the enhancement the engineer submitted so I could escalate if needed. They automatically transitioned support engineers in another geography at shift end without any drama or repetition from me. All within 12 hours.
Google has realized that building up business to business support networks is a profitable approach.
Customers get nothing, because customers don't pay money. Customers are the product.
