Dell Server Support - Not working

Good day. I have been trying to open a ticket via Dell tech support web-site ( https://techdirect.dell.com/Portal/TechnicalSupport.aspx ) 

However all attempts result in  Technical Support not available at this time, please try again later.

I have tried with different service tag machine, incognito mode, different browser, clearing cache and cookies. Still no go. What's up with that?
