The request from Monsidobot is made because Acquia Web Governance must verify the status of the link. Unless you are a client, Acquia has no interest in the content of your website and will not save any data nor use it in any way outside of the response code for verification of the status of the link.
crawl-delay on robots.txt if the connections per minute setting on the domain is NOT set.monsidobot. If that does not exist, then crawler looks for googlebot.To summarize, Monsidobot never goes below 2 seconds in order to avoid overwhelming the servers, even if users request less, and Monsidobot never waits more than 10 seconds to continue the crawl, even if a site is overly-conservative. Sites that request between 2 and 10 seconds are respected exactly, outside of that range the system overrides the request.
