Cannot access Google services through HTTP (only HTTPS)
It is most likely not related to your upgrade. I habe no problems with Yosemite:

$ curl http://google.com
&lt;HTML&gt;&lt;HEAD&gt;&lt;meta http-equiv="content-type" content="text/html;charset=utf-8"&gt;
&lt;TITLE&gt;302 Moved&lt;/TITLE&gt;&lt;/HEAD&gt;&lt;BODY&gt;
&lt;H1&gt;302 Moved&lt;/H1&gt;
The document has moved
&lt;A HREF="http://www.google.ch/?gfe_rd=cr&amp;amp;ei=IQgMVciNLuKX8Qev3oD4Dg"&gt;here&lt;/A&gt;.
&lt;/BODY&gt;&lt;/HTML&gt;


Check your router/firewall and network.
