Registration for TechDirect not functional

I need to use the Dell Warranty API that is in your TechDirect site. However, I have been unable to register there. There has been a banner saying "We are currently experiencing registration issues and are working to resolve them." for over a week now, and indeed the registration does not work. Further, the "contact us" page on the TechDirect site also does not work, and also any email address for TechDirect is non-deliverable. Thus I find myself writing here as I see no way to contact TechDirect support. Hopefully someone can instruct me in how to register for TechDirect.

Thanks,

Richard.
