Planned Parenthood, planned “hacking”?

Starting with the body tag with a suspicious attribute: `data-page-category="Under Attack Campaigns"`

    <body class="site_down_template no-write edit-disabled"
		 data-page-category="Under Attack Campaigns"
		 data-page-type="Site Down Template"
		 ontouchstart="">

The headline on the main page has since removed the text "Our site is down due to extremists", but the phrase still remains in some metadata in the head:

    <meta name="title" 
          property="title" 
          content="Our site is down due to extremists :: Planned Parenthood"/>

An image has since been removed:

    <meta name="og:image" 
	      property="og:image" 
	      content="/images/planned_parenthood_is_under_attack.png"/>

Reports that Planned Parenthood tweaked CSS and changed their story on Facebook multiple times:
