by Kushal R. 23 Jan '20

Hi all, Anyone from Verisign available here and can contact off the list? It appears that a couple of our prefixes are being blocked from reaching a root DNS server hosted there. Thanks. -- Kushal R. | Management Office: +1-8557374335 (Global) | +91-8080807931 (India) WhatsApp: +1-3104050010 (Global) | +91-9834801976 (India) host4geeks.com host4geeks.in

Prefixes blocked by Verisign, can’t reach Root DNS Server?
by Nandipati, Naveen 23 Jan '20

23 Jan '20

Hi Kushal, As discussed privately this was resolved by forwarding traffic through an alternate upstream carrier. The issue arose due to lack of return path from Verisign to your network through the common peer and can also be resolved by announcing all your internal prefixes to our common peering partner. Feel free to reach out for any further support from Verisign. ---------- Thanks Naveen

Spectrum technical contact

We have had a DOS attack for over 12 hours. I simply want them to null route or black hole an address. The traffic is filling one of our circus with them. The farthest I got was them telling me they can't do route changes because we're not public safety. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373

Provider Suggestions for Diverse 10g Wave CHI-NJ
by Josh Niec 23 Jan '20

23 Jan '20

Hey Nanog, Could anyone suggest providers for a diverse/alternative 10g wave service between Equinix in Chicago and Equinix in New Jersey (northeastern part of the state)? Currently we have a 10g wave service via the infamous Spread Networks low-latency path between the two locations, but are looking for a second that is completely diverse with no overlaps between the two data centers. Our current provider is Crown Castle Fiber, and half of the segment, from the Ohio area to New Jersey, is leased from Zayo (who purchased Spread) by CCF. I want diverse carriers for this other path, so Zayo/CCF are not an option. I’ve checked with CenturyLink/Level3 who are unable to provide a completely diverse path. I have also reached out to Verizon who have been dragging me through a 3 month+ long process with no proposals so far (they wanted me to sign the contract before showing me the actual route of the circuit, with no guarantee that it wouldn’t overlap).

A survey on performance diagnosis for Network functions/middleboxes
by Yu, Minlan 22 Jan '20

22 Jan '20

Dear Nanog community, Today's networks (data centers, ISPs, and enterprises) all run many hardware middleboxes and software network functions. The performance of these components is critical for network management and user experiences. However, when performance problems happen, it often takes a lot of human efforts to instrument and debug these systems especially when many network functions interact with each other and with traffic dynamics. We are a group of researchers from Harvard and AT&T who are building new diagnosis tools that can automatically find potential root causes for performance problems in network functions (especially those tail latency problems that are hard to diagnose). We're reaching out to the NANOG community to understand the performance problems you have seen and your needs on diagnosis tools. This will greatly help us to incorporate your needs in our tool. We plan to release our debugging tool for the community to use. We greatly appreciate your help in filling out the survey below. It should take less than 10 minutes to complete. The survey and the collected data are anonymous (so please do *not* include information that may identify you or your organization). All questions are optional, so if you don't like a question or don't know the answer, please skip it. In the survey, we use network functions as a general term to represent both hardware and software middleboxes. A summary of the aggregate results will be published as a part of a scientific article later this year. Survey URL: https://docs.google.com/forms/d/e/1FAIpQLSdx1j2BZzk_iEuIqHLDF20Rv_LuxLcrGze… We would also be extremely grateful if you could forward this email to any operator you know beyond this NANOG mailing list.

5G roadblock: labor
by Michael Thomas 21 Jan '20

21 Jan '20

https://www.politico.com/news/2019/12/29/big-barrier-trump-5g-america-089883 An interesting article on the road to 5G that they need to about double the size of the workforce to roll it out. I expect that this affects some of you directly. But one of its premises seems a little shaky to me: has the US ever led the pack rolling out new network technology? I always thought it was Japan and South Korea that were years ahead of us. In silicon valley and SF it's still very rare to see FTTH. I'm not sure why we would expect to get to 5G any faster than we normally do. Mike

Internet services in Antarctica
by Ask Bjørn Hansen 20 Jan '20

20 Jan '20

Hi, I have a hobby project running DNS service to people looking for NTP public servers. I noticed that the DNS servers apparently get ~5 thousand queries per day from IPs that the GeoIP database we use claim are in in Antarctica. It’s less than 0.0001% of the overall DNS queries, but it made me curious what it’d take to make the service work better there. I imagine the internet service is fragmented between the various stations with each being best connected to a particular country? Does anyone have contacts there that I could talk to? I imagine (some of?) the stations would have a local NTP service as part of their compute facilities. Ask
