Hi Justin, thanks for your question, I'll do what I can to address it.
First of all, as you rightly mention, a suspension is an extreme measure, reserved for use when all other efforts have failed (including warning mails, grace periods and more, depending on an account's relationship with us). Of the vast number of total customers using GCP, the number of people posting here is a very small sample size, and I would not draw too many conclusions from it. As you surmise (and as we've commented in the past) a suspension is more likely for new accounts, in large part because most policy violations happen with new accounts (and many are intentional fraud or abuse) or billing problems (e.g., never intended to pay). There are also numerous edge cases such as legal compliance issues and account hijack scenarios that make it hard to say "never."
Paying customers that are not violating our policy have little to worry about. In particular at the level of spend you're talking about, you definitely qualify as a customer that we have an ongoing relationship with, and we hold ourselves to an even higher bar in that case. In fact at that level of spend and because you're running a business, it's fairly likely that you are paying by invoice vs. a credit card. We have made even stronger statements about suspensions for customers paying via invoice (via the blog post linked below). If you are not, I would suggest that you look into it. While we sometimes encounter customers that are optimizing to receive rewards (points, miles) by using their credit cards in this manner, many people have posted elsewhere about the fact that credit cards are not necessarily the most reliable way to transact large payments for critical business services.
In June of this year there was a widely discussed incident involving a business customer who regrettably was suspended due to some handling errors on our part. What's worse, we incorrectly sent a notice saying the account would be unrecoverable after 3 days (instead of the reality, which is 30). We took that incident and the broad feedback it generated very seriously, and have thoroughly reviewed and improved (and continue to improve) our notice, account handling procedures and review processes. We outlined those commitments shortly afterwards in a
blog post you can read here, and I'd also suggest reviewing our
guidelines about suspensions.
Also, and mostly for future readers of this post, I want to reiterate perhaps the most important thing: if you are suspended, your first line of support is NOT posting here on an immortal "centithread." While several Googlers monitor this forum, responses are not guaranteed, and there is no SLA on the time lag. Instead follow the guidance in the notices you received, which should outline the nature of the problem and provide corrective options (such as appealing, contacting us to resolve the issue, etc.). Failing that or perhaps in parallel, any customer experiencing issues with their account can
contact Billing Support to receive help (no paid support plan is necessary, however if you do have a support plan - also a good idea for a serious business - you should file a case through your support portal since it will ensure that all appropriate information is tied to that case).
In closing, I want to state that while Google is often characterized otherwise, I can assure you that there are many real, living and breathing humans behind these services and our support procedures, and we care very deeply about serving our customers well. Suspensions receive human review. That said, we're human, and we sadly make mistakes. Sometimes the checks we've put in place to try and catch these mistakes also fail. In the spirit of our SRE philosophy of "blameless postmortems" we do everything we can to analyze those mistakes, listen to feedback, and make improvements.
I hope this helps clarify things some. Thanks again for your question, and for being a Google customer!
