Pulling of Network Maps
by Mike Hammett 02 Nov '23

02 Nov '23

Has anyone else noticed a trend of some network operators that previously offered street-level detailed maps, not only upon request, but also posted publicly have started to only provide them upon quotes? Not even the popular online mapping services have current-enough-to-be-useful maps. The claim is that it's proprietary. A) It wasn't before and B) No it isn't. Everything you've ever done is a FOIA request or 811 design ticket away. I'm not sure how this helps the companies. It certainly makes it harder for me trying to piece networks together when they won't tell me where they are until I give them A and Z locations. If it's too hard for me to figure out where you are, you just plain won't get the sale. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Charter DNS servers returning invalid IP addresses
by Jason J. Gullickson 01 Nov '23

01 Nov '23

I've been working for a week or so to solve a problem with DNS resolution for Charter customers for our domain bonesinjars.com. I've reached-out to Charter directly but since I'm not a customer I couldn't get any help from them. I was directed by a friend to this list in hopes that there may be able to reach a Charter/Spectrum engineer who might be able to explain and/or resolve this one. A dig against Google's DNS servers correctly returns 4 A records: dig bonesinjars.com 8.8.8.8 ; <<>> DiG 9.18.12-0ubuntu0.22.04.3-Ubuntu <<>> bonesinjars.com 8.8.8.8 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 31383 ;; flags: qr rd ra; QUERY: 1, ANSWER: 4, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 65494 ;; QUESTION SECTION: ;bonesinjars.com.

165 Halsey recurring power issues
by Babak Pasdar 01 Nov '23

01 Nov '23

Hello, I wanted to get some feedback as to what is considered standard A/B power setup when data centers sell redundant power. It has always been my understanding that A/B power means individually unique and preferably alternate path connections to disparate UPS units. A few months ago, 165 Halsey took us down for several hours. They claimed that a UPS failed causing this issue. Our natural reaction was that we have A/B redundant power so a failed UPS on the A circuit should not take down the cabinet. Joe the facility manager claimed that industry standard A/B power means two circuits to the same UPS, which makes no sense to me. They committed to move us to A/B power with redundant circuits to disparate UPS units. However, we had a multi-hour outage again in that site this weekend. At first glance it seems to be the same problem. We have checked with all of our other data center providers who have confirmed A/B power is in fact individually unique connections to disparate UPS units. 165 Halsey's definition of what constitutes redundant power seems unique. Why would anyone pay extra for a second connection to the same UPS? However, I wanted to get feedback to see if I am taking crazy pills here 🙂 None-the-less, we have lost all confidence in this facility. Best Regards, Babak

NET zone operational announcement: DNSSEC algorithm rollover
by Wessels, Duane 31 Oct '23

31 Oct '23

Verisign will soon begin the transition to DNSSEC algorithm 13 (ECDSA) for the NET zone. Over the next few days, algorithm 13 signatures will start to appear in the zone, followed by the algorithm 13 DNSKEY records. We expect the DS record for the NET zone to change from algorithm 8 to algorithm 13 on or around November 8th. Additional information can be found at our blog post and DNS-OARC presentation URLs below: https://blog.verisign.com/security/dnssec-algorithm-update/ https://indico.dns-oarc.net/event/47/contributions/1012/ We expect no operational impacts for end users, but please feel free to reach out to us with concerns or any observations of anomalous behavior related to this algorithm rollover.

Cisco 15454 Multishelf
by Michael Lambert 31 Oct '23

31 Oct '23

Does anyone have any experience with converting a Cisco 15454 multishelf configuration back into single shelves? A suggestion from the TAC some years ago involved putting a “clean” processor board into each shelf and rebooting it into single-shelf mode. The GUI suggests it’s possible to accomplish this by pointing and clicking (in the multishelf configuration tab). Any hints (probably off-list since I doubt that this is a platform still of interest to many) would be welcome. Thanks, Michael
