If only the news reporting was not as stupid as "internet is not working at UPC", instead of DNS resolvers at UPC crashed, here's what you can do...

Anyway, I didn't even notice since I run knot-resolver at home.

I wonder what it will be like connecting Facebook back to the internet, thundering herd and everything...



I suspect that the DNS aspect will be fine. The middle DNS servers only need one valid response to cache it for $TTL, but they can't cache SERVFAIL.


> but they can't cache SERVFAIL.

Correction: according to Cloudflare's blog post, some do cache errors as well.


I mean connecting your company to the internet when you have billions of devices waiting in the line to fetch updates, or whatever.

Will not that be an issue? Re-enabling routing to such a massive internet service...


I suspect it will slowly get there. We'll find out, it is recovering now.
