no responses from Coreldraw newsgroups.

I have been getting no response from any community.coreldraw.com newsgroups since 11/16. I can access the website, obviously, but my newsreader just stopped getting responses, and I can't ping it, either by name or ip address.
I believe there was maintenance recently.
Is there a change that I need to know about?
I have not changed anything unless MS snuck something in under the covers while I wasn't looking.
