CLS to CLS Latency info
by Mehmet Akcin 11 Nov '18

11 Nov '18

Hello there I have been searching for CLS (Cable Landing Station) to CLS latency infirnation for submarine cables. I was able to identify only a handful of them via sales catalogs. I am still missing like 320~ systems, does wnyone have this info available? If i can’t find the data, i am going to formulate from lentgh of fiber diveded by speed of light on fibre (~ +\- resistance) but I really would prefer actual ping ;) This is for www.networkatlas.org project. Thank you in advance! Mehmet -- Mehmet +1-424-298-1903

Cogent charging 50/mo for BGP (not IPs, the service)

Has anyone else dealt with this mess? Even my Cogent rep admits it's unique to their business. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373

Zayo is not merely Above.net <http://above.net/>. Zayo is a massive rollup of many fiber providers. It has acquired over 30 other networks. Joe McGuckin ViaNet Communications joe(a)via.net 650-207-0372 cell 650-213-1302 office 650-969-2124 fax

GTT Woes
by Laurent Dumont 09 Nov '18

09 Nov '18

Hi Folks, I was expecting a quiet weekend but it seems that is not the case. We have an IP-VPN circuit in Connecticut that feeds back to Montreal. We have a base-line of 15MS over the past few months which fits with the distance. We have a previous incident a week and a half ago where it jumped to 50MS for 5 days. This was resolved by GTT and caused by a failover to a "protected" path due to an alarm that wasn't properly handled for all that time. We had a really bad time with their Support/NOC and are quite stunned at how poorly it was handled. Well surprise, we are back in the same train. My latency jumped from 15MS to 35MS and then to 50MS a bit later. That happened on the 7th at 5:00PM Eastern and has been ongoing ever since. We've hard a very hard time getting anything out of GTT. Numerous back and forth with as much information as possible from our side. I am basically seeing the +35MS on the circuit when reaching the NY/Connecticut GTT PE straight from my device that is in the same region. I even have another GTT 12 miles from that location that has a 15MS latency all the way back to Montreal. If anyone can poke, dig or has anything for us, I would greatly appreciate it. I can provide ticket numbers and circuit ID at any time. Have a latency free weekend!

Hello, Trying to find a contact at BGPView.io (outside the useless contact form). Some of their data for our ASN has been outdated for months so I'm trying to find where they get the data from. Thanks Eric

Technical Contact at Yahoo

Yahoo have done a very good job of locking down their contact info. We have an issue where they seem to be blocking one of our CGN public addresses. Does anyone know how I can get in touch with an appropriate person there?

Re: Amazon network engineering contact? re: DDoS traffic

Zach, As mentioned before, I am open to peering (where possible) but have not received a response. My goal is to connect with someone at Amazon and work with them on a technical solution, which is why I posted asking for that here. Various factors mean that we can't just upgrade our way out of this one, and manual whac-a-mole on the sources has shown to have limited use. These attacks also impact Amazon and the networks in between the sources and targets, and they take time to handle by the abuse teams, so there are good reasons to investigate them further and find better ways to mitigate or prevent them. -John On 11/8/2018 1:12 PM, Zach Puls wrote: > Makes sense, that's understandable. Do you peer with AWS? If not, maybe opening up a peering agreement will give you a better contact, and a bit more pull when attacks occur?

As a general practice, when you detect a (D)DoS attack in progress, it would help to automatically advertise that prefix to your upstream(s) with the black-hole community. This would at least help mitigate the effects of the attacks when they do occur, even if they come from a different source than AWS. >> >> Thanks, >> >> Zach Puls >> Network Engineer | MEF-CECP >> KsFiberNet >> >> -----Original Message----- >> From: NANOG <nanog-bounces(a)nanog.org> On Behalf Of John Weekes >> Sent: Thursday, November 08, 2018 14:44 >> To: nanog(a)nanog.org >> Subject: Amazon network engineering contact? re: DDoS traffic >> >> We've been seeing significant attack activity from Amazon over the last two months, involving apparently compromised instances that commonly send 1-10G of traffic per source and together generate Nx10G of total traffic.
