enom giving Google a bad name
by Hank Nussbacher 16 Jan '22

16 Jan '22

Many of you might be following the enom weekend fiasco: https://twitter.com/enomsupport/status/1482621466151571456 https://twitter.com/enomsupport/status/1482707275529678849 https://enomstatus.com/ Thousands of domains have been knocked out. But I just found out that Google is an enom reseller: https://help.enom.com/hc/en-us/articles/115005222367-My-Domain-was-register… "Google handles all of the billing and renewals of your domain name, while Enom offers technical support to manage your domain." So who takes responsibility when a fiasco happens like this: Google or Enom? -Hank

Open source mapping of US high voltage electrical grid
by Eric Kuhnke 16 Jan '22

16 Jan '22

Possibly of interest for network operators who have inter-city circuits, where the underlying carrier is something on OPGW fiber in high voltage lines. These people seem to be making an effort at mapping out high voltage lines, hydroelectric dams, substations, etc. https://openinframap.org

Does anyone have a contact for AS 6453 or are there any AS 6453 folks on list? Seeing some routing trouble from their customers to the US. Thanks, -Drew

Useful ping targets for end-users?
by Adam Thompson 15 Jan '22

15 Jan '22

Before you start reading, yes, I fully understand how silly this question is. But I need to give _something_ to a customer who has the ability to run ping/traceroute but nothing else. (And they have an intermittent latency problem that we haven’t been able to isolate yet.) Does anyone curate a list of “useful” ICMP responders that are at least kinda-sorta reliable/expected to continue responding? For example, all the major anycast DNS cloud providers respond to ICMP, but I don’t really want to tell my customer to ping an anycast IP address because the RTT results will be useless data (for comparative purposes). I’m also not excited about providing random router IP address for what should be obvious reasons. There are some IPs that my routing paths that should be stable, but between routing changes and control-plane policing, those aren’t awesome. I’m looking for IPs I can suggest that are well outside my network. Restatement: yes, there are much better ways to diagnose problems, but my customer can only run ping & traceroute (and pathping, I suppose) and is capable enough to run those tools and self-assess before calling me. It sounds foolish to even ask, but maybe there’s a resource out there I don’t know about… -Adam Adam Thompson Consultant, Infrastructure Services [MERLIN] 100 - 135 Innovation Drive Winnipeg, MB, R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) athompson(a)merlin.mb.ca<mailto:athompson@merlin.mb.ca> www.merlin.mb.ca<http://www.merlin.mb.ca/>

BGP Route Monitoring
by Sandoiu Mihai 14 Jan '22

14 Jan '22

Hi I am looking for a route monitoring product that does the following: -checks if a specific bgp route from a specific neighbor is present the BGP table (in some vrf, not necessarily internet routed vrf) of an ASR9K running IOS XR -sends a syslog message or an alarm if the route goes missing The use case is the following: we are receiving same routes over 2 or more bgp peerings, due to best route we cannot really see at the moment if one of the routes ceased to be received over a certain peering. Alternative approach: a product that measures the number of bgp received prefixes from a certain peer. Do you know of such product that is readily available and does not require ssh sessions to the routers and parsing the outputs? I am trying to find a solution that does not require much scripting or customization. Many thanks. Regards Mihai

RE: home router battery backup
by Shawn L 13 Jan '22

13 Jan '22

In $dayjob I work for a telco that deploys fiber to the home. If we are providing voice services over fiber a battery backup is installed (we maintain) that powers the customer's phone in the event of a power outage. It does not power their router, etc. 99% of the customers do not install a UPS for their router, etc. We try to explain that to customers, but we still get calls that they can't get on the Internet when their power is out. -----Original Message----- From: "Scott T Anderson via NANOG" <nanog(a)nanog.org> Sent: Wednesday, January 12, 2022 12:35pm To: "nanog(a)nanog.org" <nanog(a)nanog.org> Subject: home router battery backup Hi NANOG mailing list, I am a graduate student, currently conducting research on how power outages affect home Internet users. I know that the FCC has a regulation since 2015 (47 CFR Section 9.20) requiring ISPs to provide an option to voice customers to purchase a battery backup for emergency voice services during power outages. As this is only an option and only applies to customers who subscribe to voice services, I was wondering if anyone had any insights on the prevalence of battery backup for home modem/routers? I.e., what percentage of home users actually install a battery backup in their home modem/router or use an external UPS? Thanks. Scott Reference for 47 CFR Section 9.20: [ https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-9/subpart… ]( https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-9/subpart… )

"Hackathon" Solves Real-World Tech Issue + Committee Nominations + More
by Nanog News 13 Jan '22

13 Jan '22

*“Hackathon” Solves Real-World Tech Issue* Code Developed during NANOG Hackathon Goes Live Hackathons are an essential part of NANOG conferences. They are designed as a “fail forward” space where mistakes can be made as learning, having fun + building community is the prime objective. And sometimes this perfect cocktail of sophisticated fun leads to solving real-world technical issues. The work done at the NANOG 83 Hackathon improved the PeeringDB Simple Search and resolved a vital search issue. Thus, allowing PeeringDB (a freely available, user-maintained, database of networks, and a go-to location for interconnection data) to provide more relevant search results for the end-user. The developed code during the Hackathon, officially went live early Wednesday morning (Jan. 12). NANOG had the opportunity to catch up with PeeringDB product manager Leo Vegoda to learn more. *READ MORE <https://www.nanog.org/stories/hackathon-solves-real-world-tech-issue/>* *Now Accepting Committee Nominations* The 2022 Committee Nominations are now open and run through Tuesday, Feb. 15, 2022. Reminder, only NANOG members in good standing are allowed to serve on a NANOG committee. We are currently seeking volunteers for the Program Committee. **If you are not a member and wish to participate in the nomination process, your membership must be received by 9:00 p.m. PST on Tuesday, Feb. 15, 2022.** Click here to review the nomination process and volunteer for a committee! *COMMITTEE NOMINATIONS <https://www.nanog.org/members/elections/committee-nomination-process/>* *NANOG 84 Sponsorships Still Available * NANOG is, and always has been, dedicated to the people who make up our community. Our in-person conferences draw up to 1,500 individuals in multiple facets of network engineering, operations, and architecture, who gather with us in major cities across North America.

home router battery backup

> On Jan 12, 2022, at 5:11 PM, Scott T Anderson via NANOG <nanog(a)nanog.org <mailto:nanog@nanog.org>> wrote: > > For those individuals with backup battery power for their modem/router, do they maintain Internet access throughout a power outage (as long as their backup power solution works)? I.e., does the rest of the ISP network maintain service throughout a power outage? The answer is, “It depends.” Plymouth in Michigan recently had a substation fire that took out a large fraction of the city. Restoration of the substation was a lengthy process as mobile transformers and the like were required. My Comcast connection was only down for a short time until some generators were dispatched to some pole-mounted equipment within the city. Since my local power comes from a different substation, the brief Comcast outage was the only noticeable event. I frequently hear the UPS beep for short interruptions, confirming that the battery is still strong. My original UPS was installed to ride through momentary outages and to inhibit spikes since spikes and arbitrary power shutdowns can cause damage to both data and equipment. My cable modem, router, network hub, several computers and monitors, and task lighting are all protected from outages for a decent interval followed by a spike-free shutdown. The latter is important, especially as compared to the transients occurring as trees fall on power lines. The 2003 midwest blackout was days long. I helped a friend wire his well pump to a portable generator so one could “flush”. I then grabbed my laptop and took refuge up north outside the outage area. At that time, WFH had long been part of my vocabulary.
