Problem/Motivation
Whenever my sitemap is submitted, it generates this log message alert:
Submitted the sitemap to https://www.bing.com/ping?sitemap=https://www.mysite.com/sitemap.xml and received response 404.
Pinging Using a HTTP request by submitting it directly to Bing will return a HTTP 410 error (page moved or deleted).
According to this article (https://www.ctrl.blog/entry/sitemap-ping-indexnow.html), sometime between December 14th and 22nd, Bing stopped accepting new ping submissions to its XML Sitemap Ping service.
Steps to reproduce
Run cron to submit your sitemap, then check recent log messages on website.
Or type in browser address bar: https://www.bing.com/ping?sitemap=https://www.mysite.com/sitemap.xml
Proposed resolution
Remove Bing as an option if not fixable.
