We got fed up with Google Cloud yesterday as they unplugged things without warning even if we have the paying accounts in place. I know it is a small case to them and they won't care. We still need to raise the voice and that they need to know they are holding a wrong mindset and wrong policies on their users.
To save your time, you may jump directly to paragraph#3.
It's because they did some weird integration with a common payments system that is broken. If you call their customer support, they will bounce you from the cloud Dept to the wallet team to payments and so on...it's a classic big company issue trying to consolidate things like payments across many products.
That is interesting to learn that it is the wallet team handling the payments, not someone in the Cloud team. But the issue here is not payment, it is how they handle the free tier users. And they mess up in the case when several owners together in the same projects.
Funny reading this about to get into a call with Rackspace trying to rationalize our accounting department not paying some huge invoices well past due... luckily they haven't turned anything off though. Can't say anything negative about them in that regard.
Uptime is the first most important thing for internet companies! Guarantee the upmost uptime builds great reputations for a cloud provider, don't know why Google still don't get it.
