1.1.1.1 still not working from Telecom Argentina

1.0.0.1 works just fine.

1.1.1.1 on the other hand gives “connection refused” on the browser. Responds to pings just fine but it is unreachable as DNS.

Can you run through these few steps and post the results here?

Here are the results:

I hope this helps solve the issue.

Ohh you juicy, juicy 1.1.1.1 :wink:

Does Telecom Argentina really hijack the IP at this point?

Let me try with Level3 and report back

Our backbone doesn’t know the route to 200.3.81.45:

Since 1.0.0.1 is working on all ISP i’ll concentrate on 1.1.1.1

So it seems it’s Telecom Argentina the responsible for this timeout as Level3 appears to be working.

To be fair, I cant reach any of the host*.telecom.net.ar hosts in the traceroute, but what caught my attention was the fact how close 1.1.1.1 is supposed to their network, when 1.0.0.1 goes via seabone.net.

To me this looks like a classic misrouting to an actual machine (notice that it actually responds to the traceroute) - be it intentionally or not.

@tecnogaming, can you adjust the title? It doesnt seem to be all of Argentina not liking Cloudflare, only TA :slight_smile:

Indeed. Adjusted.

Any idea how can we fix this?. I am in contact with my ISP and I could contact Telecom through them but I don’t know how to request a fix for this.

You could certainly try contacting them, but knowing telecoms I am not sure if a complaint from a single person would be heard (particularly within any reasonable amount of time).

Your ISP should (hopefully) have the right contacts (and interest to get this fixed :wink: ), alternatively maybe Cloudflare can use their channels :slight_smile: @cs-cf
