is not reachable from the Fastweb S.p.A network


The DNS service was working until a few days ago.
Suddenly my browser stopped resolving domains and I was surprised to find out that the Cloudflare DNS was unreachable via tracert.

I then switched to which is still working.

I tried to contact the ISP but they haven’t replied yet and I am not sure if they will.
Any confirmation as to why is unreachable would be appreciated.

This is definitely related to something local, based on the trace route. It could be a configuration issue on your first router, or your ISP.
