Problem asn 52666 traffic


#1

Good afternoon,
We are blocking our AS and AS from our customers, hours it works hours for. Could you give us a feedback on what happens? AS 52666.
Thank you!


#2

Can you be more specific about the error you are seeing and the host or URL?


#3

All traffic originating 104.0.0.0/8 that is hosted by the cloud to have communication through any of the links I have, including the ASN of the clients behind our edge.
ASN 52666 - Our ISP.
No site opens.
I think there is a blockage of our AS.


#4

Would you be able to provide a traceroute to cloudflare-dns.com to help our engineers in diagnosing the potential source of the issue?

Thanks!

Thanks I have passed this along to our network team for investigation.


#10

I believe we are making a routing change and notifying the ISP’s NOC of the issue/ change. Can you retest and see if you can access now?


#11

Okay, we’re working right now.
We will look for IX.Br for solution.
Thank you!
