When a product link stops working.
A broken-looking page is not one single condition. Keep the original URL intact, identify the failure and avoid manufacturing a replacement destination.
Start with the source record
Open the exact FansSheets detail URL recorded here. Do not rebuild a link from the product title or copy an identifier into an undocumented template. A title can change; the observed URL is the evidence trail.
Distinguish the result
404 or 410The source reports that the page is missing or gone. Keep the record out of current results until a new source page is independently verified.
BlockedA 403, 429 or challenge page may prevent automated verification. Mark it blocked; do not call it dead or verified.
TimeoutA temporary network failure is inconclusive. Preserve the previous known-good dataset and retry later with a respectful interval.
Agent conversion issueIf FansSheets loads but one agent does not, the problem is the product-specific agent link. Do not replace it with the agent home page and call the product available.
