Thanks. I checked it out, and I find no issue. No warnings on any browser. It belongs to Swisscom. Norton and McAfee say it's safe. I see no reason to remove it, but of course you follow any external links at your own risk.
Oops! I didn't see your post before I edited. I took a look, and the site had a different look and feel to it than any other Kt ZH website. So I removed the links from the post.
I think at this point contact tracing is done anyway.
