Fix DNSSEC

[bobvandevijver]

You should really fix your DNSSEC configuration: it is now marked as bogus, which means that less and less people will be able to visit the site. You can either remove DNSSEC completely, or configure it correctly.

See https://dnsviz.net/d/ckeditor.com/dnssec/.

Thanks for reporting @bobvandevijver.

@vokiel could you take a look on this?

It seems like the issue is valid, but we can't really fix it as the issue is on our CDN provider side. For a reference, you can see this @vokiel comment about the similar problem and workaround suggestions - #3596 (comment)

We will be looking into this issue and mostly be waiting for upstream resolution but it doesn't seem like we will be able to fix it right away.
