Suppliers of Optics, Cables, and Parts and Support in Argentina
by nanoguser99 26 Jan '23

26 Jan '23

Nanog, Our organization is US based. South America is a difficult region to procure parts in but Argentina is particularly difficult. Our current process is to ship spare gear to Argentina but we get hit very hard with import duties. I'm looking for a local supplier of Optics, Cables, and Parts (drives, RAM, etc.) locally in Argentina. As a second initiative we are exploring putting a few systems under a support contract so we don't deal with the headache that comes with navigating importing gear there. We would be putting a few generic supermicro servers (CPU, RAM, Motherboard, disk) and some network equipment (Cisco\Juniper) under support. Any help from anyone who has navigated this would be appreciated. -Nanoguser99

Starlink routing
by Michael Thomas 24 Jan '23

24 Jan '23

I read in the Economist that the gen of starlink satellites will have the ability to route messages between each satellite. Would conventional routing protocols be up to such a challenge? Or would it have to be custom made for that problem? And since a lot of companies and countries are getting on that action, it seems like fertile ground for (bad) wheel reinvention? Mike

Need an experience feedback Cisco 8000V
by Network Operation Center - Axess OnLine 23 Jan '23

23 Jan '23

Dear members, Our team consider to changer our PE router which is connected to our 300 client using MPLS L3VPN and L2VPN, to cisco 8000V Is there any company actually using 8000V in production?, I need some advice, because I wonder a virtual router make some problem or not. Up to now, I haven't heard of use of virtual router in ISP. What I want to know most is, 1. Is it stable? Are there any existing bugs that would cause problems? 2. Compared to router physical, What were the advantages that brought you? Best regards. Seungtaek OH

Know this is a longshot, any chance anyone from the txt.att.net domain might be able to help us with what we believe is a blacklist block or possibly an outage? We deal with 911 cad dispatching and is affecting first responders so looking to see if there is a faster way to resolution. Thanks, in advance.

Level 3 A and B DNS resolvers
by Josh Luthman 20 Jan '23

20 Jan '23

I'm well aware these are not to be used by the public for DNS. My only concern is that it's used as one of several external hosts to look outside of our network. This is monitored through Spectrum (Charter) in southwest Ohio. Maybe a closer server was taken offline or it was unplugged for a coffee maker. Just reaching out to see if there's any insight at all. Since ~Dec 8 it looks like we added a bit of latency: [image: image.png] DNS resolution has had quite some issues since then: [image: image.png] 4 10 ms 9 ms 8 ms lag-15.troyoh0901h.netops.charter.com [65.189.190.189] 5 17 ms 14 ms 13 ms lag-39.dytnoh5501r.netops.charter.com [65.29.38.112] 6 10 ms 10 ms 10 ms lag-28.rcr01clevohek.netops.charter.com [65.29.1.46] 7 15 ms 40 ms 10 ms lag-2-100.rpr01cleyohdh.netops.charter.com [65.29.33.239] 8 * * * Request timed out. 9 18 ms 17 ms 17 ms ae2.3601.ear1.Washington12.level3.net [4.69.148.45] 10 18 ms 17 ms 17 ms a.resolvers.level3.net [4.2.2.1] Josh Luthman 24/7 Help Desk: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373
