what drives me mad is that it's not even underrated! everyone knows, everyone has been talking (and complaning) about this for something like 15 years!
I personally know of 2 big GCP customers who, over the years, left GCP because of this and the impact it had in critical situations. This very feedback was given in both cases to people considerably high up on GCP's ladder and... nothing's ever changed.
I'm sure plenty other big migrations off GCP provided the same feedback, to no avail.
When Diane Greene first and then Thomas Kurian became Google Cloud CEOs people thought that finally, due to their previous experiences in very Enterprise-aggressive companies, they would improve massively on that front.
Did they improve the situation? a bit. Massively? bringing GCP finally on-par with anyone else (not better than anyone else, just... the same)? nope, not even close.
