Ok, it's not goggle.com or one of the more well-known google sites but the site survey.googleratings.com is powered by Microsoft's IIS running ASP.NET. I only noticed this after I received an Adsense survey invitation with a link ending in .aspx. I wouldn't be surprised if the survey results are stored in an SQL Server database.
Google is the actual owner of googleratings.com, so one must assume the site is managed by a third party company, keeping the survey operations away from googleplex. I'm pretty certain any google developer who'd even consider using Microsoft products will be severely humiliated by his peers 🙂
