Site indexed in Bing Webmaster Tools but not served in Bing results since 15 October (REQ00362631, REQ00369038)

Since about 15 October 2026, madrobot.blog has effectively disappeared from Bing results, and from DuckDuckGo, Yahoo and Ecosia.

Our pages are still indexed. URL Inspection reports https://madrobot.blog/2026/10/19/aleksander-madry-returns-openai-ai-safety-security-pachocki/ as “Indexed successfully: URL can appear on Bing”, and the live test passes with no SEO issues. But searching its exact headline in quotes returns no results, and site:madrobot.blog shows only 3 pages. The Webmaster Tools support assistant reported “Site appears not served fully”.

What we’ve checked: robots.txt allows Bingbot, both sitemaps are processed without errors, there are no noindex tags, and our server logs show Bingbot crawling normally with successful responses.

MadRobot is an independent news site covering artificial intelligence, launched on 22 September 2026, with named writers, links to primary sources and a public corrections policy.

I opened support tickets REQ00362631 (18 October) and REQ00369038 (22 October). Replies to the ticket emails bounce, and I haven’t had a response yet. Could someone from the Bing Webmaster team look at whether a filter has been applied, and what we need to change to have the site reviewed?

Thank you.
