And if random account suspension is something that happens to G Suite accounts, I think the answer is that your IT department's G Suite admins can click the button to un-suspend your account.
Google normally suspends accounts (notification after suspension with no real info) for heavily reported spam, they will suspend a ton of accounts if your domain is sending a ton of spam, even if its not via g-suite directly. This may be the case are you sure your domain is secured?
I don't know how any of my accounts could have been sending spam. I don't send unsolicited email, and I forward messages from those other four accounts to my primary email account, so I hope I would have noticed a spam problem. But because I cannot log in to anything, and didn't get any information or notification from Google, I can't be sure, of course.
I am subscribed to a lot of mailing lists and I wonder if, given my low human outbound volume, whether gmail-generated "bad attachment" bounces could have resulted in this. But that seems unlikely. More likely is someone ran a query and decided I had too many emails or was using too much G Suite storage. I look forward to hearing any information at all from Google!
I had a "personal" account which Google buggered up because it had the same email address as my GSuite one. I never even signed up for GSuite; they forced the migration sometime after they acquired Postini, and I was a happy customer of the latter (and kept paying Google for some time after the conversion).
I got locked out of the personal account, and IIRC stuck in an edge case that needed me to authenticate on Android (can't remember why - some kind of 2FA thing?). Of course the Android login screen didn't accept those @googletempaccount style addresses.
Chased Google for over a year trying to get this fixed. It was difficult reaching any live humans with powers over Accounts. Even brought it up with some devs at I/O. Lots of sympathy, but nobody interested in championing my issue.
In the end I managed to get the account partially recovered, but there are still some Google products for which my data was never seen again (e.g. lost all starred threads from Google Groups).
After the ordeal, I doubt I would entrust Google to replace my DC. Certainly not as much as a third party whose whole business is this and whose revenue depends on maintaining good customer service. Just hope they don't get bought by the juggernaut.

Its a good reason to never link a gmail address as a recovery address for gsuite - always use another free mail provider.
Also, what if the recovery address is another g suite account in a separate domain?
I personally never link or login with my personnal accounts on work devices, nor do I use work accounts on personal devices.
T&C violations disable an account and any linked recovery addresses (and accounts with the same recovery phone number).
If an account is disabled, all resources associated are disabled and deleted 30 days later.
A GSuite domain is considered a resource 'owned' by the first admin, so if that account is disabled, so are all in the domain. If it is deleted, so is the domain.
Well, I guess you can't log in to your own Windows computer. A brave new world as it is.
It was a nice coincidence that someone gave me a Gmail invitation around that date.
However, I had been burned once, and now I have my own domain for the important emails, and that Gmail account is used for things that can be spam.
Lesson: Any huge provider can suspend accounts at will and there's nothing you can do about it.
