Does anyone have any contacts at Facebook that are working on their Middle Mile infrastructure project? All attempts to figure out whom to talk to in that regard have been met with failure. Thanks, -Drew

End to End testing
by Fawcett, Nick 12 Dec '19

12 Dec '19

Anyone have any suggestions on devices that I can put at two points in the network to test packet loss, latency, jitter etc. I was thinking of maybe engineering my own using a couple of pi's, but the downfall is they don't have SFP ports. I'm looking for something that's portable and easy to configure and drop in. Thanks. ~Nick -- Checked by SOPHOS http://www.sophos.com

DDoS attack
by ahmed.dalaali＠hrins.net 10 Dec '19

10 Dec '19

Dear All, My network is being flooded with UDP packets, Denial of Service attack, soucing from Cloud flare and Google IP Addresses, with 200-300 mbps minimum traffic, the destination in my network are IP prefixes that is currnetly not used but still getting traffic with high volume. The traffic is being generated with high intervals between 10-30 Minutes for each time, maxing to 800 mbps When reached out cloudflare support, they mentioned that there services are running on Nat so they can’t pin out which server is attacking based on ip address alone, as a single IP has more than 5000 server behind it, providing 1 source IP and UDP source port, didn’t help either Any suggestions? Regards, Ahmed Dala Ali

NFL Sunday Ticket - Online Streaming service
by Justin Krejci 10 Dec '19

10 Dec '19

I am looking for a contact in the network group (may be called National Escalation team or NatEsc team internally) within AT&T/DirecTV pertaining to the NFL Sunday Ticket online streaming service. I have been attempting to work through their normal support process for quite some time, they are extremely isolated and handicapped in the support center and I am so frustrated at the impossibility to get any traction through their call center to deal with a network related issue. I have had 4 cases go to their escalation team and they all mysteriously close with no real or valid resolution. I've spoken with about 4 or 5 supervisors in their Tulsa call center and they are unable to do much. It has been a nightmare and I am hoping someone has a contact they can get me in touch with.

"what ip address can I look in netflow for traffic destined to which is part of this attack?" Anyone trying to help you is going to want to know what destination address in your network is receiving this traffic... not providing same after ~15 emails is going to make your situation not get better.

Elephant in the room - Akamai
by Kaiser, Erich 09 Dec '19

09 Dec '19

Lets talk Akamai They have shifted 90% of their traffic off IXs and onto our full route DIA, anyone else seeing this issue or have insight as to what is going on over there? We have been asking for help on resolution for weeks and all we get is we are working on it and now we get no response. We were even sent an LOA and when the DC went to go put in the x-connect their patch panel was full. How do they not know if they have ports open or not? I have even reached out to an engineer who is on this list and he does not even respond. The last two nights the traffic levels to them has skyrocketed as well. Any insight?

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address.
