The exact same has happened with CodeSandbox, Google Domains had blocked our csb.dev (internal domain) and csb.app (domain for projects) without any warnings. It took us two days (of downtime!) to get them to lift the block. But then after 3 weeks, they did the exact same thing! They blocked us again for reports without warning. Luckily we had a fallback domain so that there was not much service disruption, but it was extremely frustrating working with them on this. After 3 sudden blocks from them, they now give us a warning before they're planning to block us, but it took many calls before we got to that stage.
