Ask HN: Windows XP SP2 and IE 6.0 sites won't load?

I am installing Winddows XP SP2 on virtual machines for legacy development. I found out Google.com does not load in IE 6 and bing.com does. Going to ninite to download installers also does not load. Bing.com loads fine and I can download Firefox good thing it still works with XP SP2. Firefox seems to load ninite and uses Yahoo search now. But google.com still gives me a page not found even in Firefox.

Is Google blocking old OSes and Web Browsers, or is this a thing with XP Certificates expiring or something. I want to use XP to develop some older Visual Studio languages with VB 6.0 and etc. Have problems running in modern Windows. Yet I can't help but notice XP SP2 can't load certain websites. Are they trying to force XP users to upgrade to a new Windows or is this just some sort of coincidence?

Edit: IE 6 does not load Google.com but the latest Firefox can. I doubt Google is having connection issues. Ninite seems to load in Firefox as well. I wonder what other websites act like that with IE 6.0? I don't use SP3 because it loads slower and it is based on Vista a but and SP2 is more stable for me.
