Chess board is invisible

I can see all of the chess pieces but the board and the squares are not visible. I am working off of a google chrome browser. There are no plugins that would be activated on this page. The issue has persisted over the past two days. Any help is appreciated.
It's a known issue and apparently is a problem on the Content Delivery Network (CDN) the site uses to host static assets. It is impacting a subset of members, some in Canada and Portugal.
Staff are aware and working with the CDN provider to resolve. Switching to 3D pieces may help; some members have had that work.
