[dns-operations] Signature expired for the DS of .ch at Cloudflare ?

[Marek Vavruša]

Hi Stephane,

We published a blog post with RCA and more details here
https://blog.cloudflare.com/1-1-1-1-lookup-failures-on-october-4th-2023/
The issue was the local resolver root zone copy was stale and not
removed from production in some places.
I'm sorry for any issues encountered.

Marek
