Why it matters
Google slows down crawling when it sees 5xx errors. Pages that were already indexed are kept for a while but are dropped if the errors keep happening.
Your server answered Googlebot with a 500-level error, so the page could not be indexed. Find out whether the errors are ongoing, fix the hosting or application cause, then validate the fix.
Google slows down crawling when it sees 5xx errors. Pages that were already indexed are kept for a while but are dropped if the errors keep happening.
Fix every affected URL first, then use Validate fix in the report. Validation can take about two weeks, and Google emails you the result.
| Check | How to tell | Fix |
|---|---|---|
| Is the error still happening? | Run "Test live URL" in URL Inspection on an example URL and compare its last crawl date with today. | If the live test now succeeds, the error was temporary; keep watching rather than changing code.[1][2] |
| Is the host overloaded or down? | Open the Crawl Stats report and look at host status and server response errors over time. | Resolve capacity or outage problems with your host, or move to hosting that copes with your traffic.[3][2] |
| Is a firewall or bot filter blocking Googlebot? | Check firewall, DNS and bot protection logs for blocked requests from verified Google crawler addresses. | Allow verified Google crawlers through instead of challenging or rate limiting them.[4][2] |
| Does the page itself crash? | Load the URL yourself and check the application error log for that request. | Fix the failing code or plugin, then confirm the URL returns 200.[5] |
A short outage usually does not. Google keeps indexed URLs for a while during server errors and only drops them if the errors persist.[5]
No. Fix the cause, then use Validate fix in the Page indexing report and let Google recrawl.[2]
