My one .xo.je is showing the same ERR_NAME_NOT_RESOLVED

To answer your question: no, the topic description is accurate. The two listed domains are affected, nothing else is.

I split your post to a separate topic, because it broke two rules of the outage topic.

Firstly, please note this one.

Different error or component? Create a new support topic instead!

The outage topics are busy so we want to keep them clean. So if you’re not sure if the issue is related to the outage, then create a separate support topic instead. That way we can check your issue directly without it getting drowned in the outage topic.

With that said, note that there also the following rule:

Include your website URL when posting in case we need to check something.

I’m happy to have a look and see why your website is not working, but you didn’t actually tell us which website is having this issue.
