Do you see sudden drops in pages indexed in Google Search Console?
The reality is that these drops don't reflect when the pages were kicked out the index.
In fact, tracking daily index status of pages shows the drop is gradual.
Showing a clear trend in certain sections of the website being slowly kicked out of the index by Google.
It doesn't happen in one big push, but gradually overtime.
The issue with GSC reporting is that it is aggregated and updates 1-2 times per week. So although the reporting shows a sudden drop. Your pages are being kicked out the index a lot earlier (days before).
