IEEE is a large professional association dedicated to serving engineers. The IEEE Web Presence is made up of flagship sites like IEEE.org, IEEEXplore, and IEEE Spectrum, mid-tier sites like Computer.org, and smaller sites like those dedicated to specific conferences.
It is unclear exactly when this started - but searches in Google for [ieee] currently return ieeeusa.org before ieee.org. This is troublesome, as users are typically looking for IEEE.org with such a general query. ieeeusa.org is a site that has a much narrower focus - it is dedicated to public policy.
IEEE.org is one of the strongest domains - I am thinking that this is a glitch of some sort. I am removing a stale sitemap that is referenced in robots.txt (though again, I'm not seeing any issues with other pages - its just two queries that are trouble: [ieee] and [about ieee]. And its noticeable in analytics
