Who is filtering me ?


#2

Which datacentre are you contacting? From your trace I can find indicators for Argentina, Sweden, and the US. I guess it will be one of them :slight_smile: Can you post the link from https://cloudflare-dns.com/help?

From your trace it would appear as if the connection stops right in Cloudflare’s datacentre, so I wouldnt blame your ISP in this case.

sounds pretty much related with this post

Dont know why says that asn data, isnt right.
I own my own ASN


#6

My ASN is 265755


#7

So, Argentine it is.

By your own AS, I presume you mean your Internet connection runs on its own network, right? The AS shown, however, does not refer to your network but to the network of the DNS server you use, which in your case appears to be your provider’s.

I am a bit confused by that cloudflare.baires3.bai.se entry as that would hint at something Swedish inbetween, but the host does not resolve and you seem to hit the Argentinian datacentre.

@cloonan / @cscharff or drop Cloudflare an email at their [email protected] address.


#8

Now its working :

I use my own /24 using my own ASN.: https://bgp.he.net/AS265755#_asinfo
I only publish my /24 on https://bgp.he.net/AS52361#_graph4

I dont know if everyone there is having the same problem.
It’s seems to be an intermitent fail.
1.1.1.1 never fails using another connection from Argentina.

So its a problem of my carrier Arsat or Cloudflare. ?
As you said it seems to be cloudflare last hop that fails.
Why 1.0.0.1 works ?
Isn’t the same?

I will email them

Is the trace still going the same route?

#11

My guess would be something got fixed in the datacentre. Did support say anything?
