UPDATE: April 15, 2019
Google says they fixed the de-indexing bug but now are reporting issues within Google Search Console.
Search Console is still recovering from the indexing issue we reported on last week. As a result, index coverage and enhancement reports were not updated recently & URL Inspector might not reflect live status, at the moment.

UPDATE: April 9, 2019
Google says they expect the error to be fixed within 12-24 hours.
We are still resolving the indexing issue that has impacted some pages. We've made further improvements and hope any remaining issues will be done within the next 12-24 hours. Will provide a further update when the issue is fully resolved.

Starting last Thursday, some website owners noticed a troubling error; their pages were disappearing from Google's index. On Saturday, Google's John Mueller assured the SEO community that the problem had been resolved. Unfortunately, that was not the case.
On Sunday, Google SearchLiaison posted the following update on Twitter:
We're aware of indexing issues that impacted some sites beginning on Friday. We believe the issues are mostly resolved and don't require any special efforts on the part of site owners. We'll provide another update when the issues are considered fully resolved.

What you should do:
If you have a page that you suspect has been affected by this problem, use the URL Inspection tool in Google Search Console. Here is how:
1) Go to Google Search Console, log in, and select the website you want to review.
2) Click on “URL Inspection”.
3) Submit the page URL you want to inspect.
4) If you see “URL is on Google”, you have nothing to worry about.
5) If the page is not on Google, select “Request Indexing”.
We will post updates as we know more.
