PTC Knowledge Base Search Unreachable

This isn't directly a Thingworx problem but for the past several days at least I have found the PTC Knowledge base search page to be broken. The page loads the normal PTC header and footer but no additional content appears on the page making the knowledge base resource unusable and inaccessible.

The issue persists through a cache clear and computer reboot and occurs in both Firefox and Edge browsers.

Does anyone else find this issue? I search the knowledge base frequently when developing and would like to continue doing so.
