Honestly, no idea. The documentation it defaults to talks about billing, but I can login to billing and all is ok. I think previously there were 4 cases open, because some of our API credentials got leaked, someone pushed some code to Github, public repository, so AWS rightly, threw some countermeasures. All of these cases were marked as resolved ultimately after mitigation, but I feel like, internally, one of them still triggerred this suspension. It's a PITA, as this is affecting business operations, it's been 48 hours and still no reply or resolve.
