U.S. test of national alerts on Oct. 4 at 2:20pm EDT (1820 UTC)
by Sean Donelan 11 Oct '23

11 Oct '23

This year's test of the U.S. national emergency alert includes something for ISPs and network operators. The wireless portion of the national test is scheduled 2 minutes (2:18pm EDT or 1818 UTC) before the main broadcast test at 2:20. Mobile phones usually receive the alert about a minute later. Radio and TV will receive the national alert a few minutes after 2:20pm. iPhone iOS 17 added a new feature for Wireless Emergency Alerts. When iOS 17 iPhones get a wireless emergency alert (WEA), it will trigger a data network query for additional information. Its a small query and response, but there are a lot of iPhones making the query at the same time (I'm assuming Apple engineer's have built in some time skew). Apple has assured FEMA that Apple's CDN and servers will be able to handle the triggered load. The iOS 17 triggered query will either be a tiny blip in the network graphs around 2:18pm to 2:22pm which no one will notice, or some CDNs and ISP operators will be wondering what that heck that spike was. If your phone is configured with Spanish, it will display the alert in both English and Spanish. “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.” “ESTA ES UNA PRUEBA del Sistema Nacional de Alerta de Emergencia. No se necesita acción.” You'll know your iOS17 device did an extra data query, if it displays a longer message (extra sentences) in addition to the messages above. "This is only a test. No action is required by the public." https://www.fema.gov/press-release/20230803/fema-and-fcc-plan-nationwide-em…

AT&T Business Center completely broken for months - is it the norm?
by Mirai Azayaka 10 Oct '23

10 Oct '23

Hi NANOG, Maybe this topic is better suited for the complaint department of AT&T but I just want to confirm if it's just me or it's just AT&T... So I'm a new customer of AT&T's DIA network and I haven't been able to make a payment since day one. (And it has been several months.) Just wondering if a completely broken internal billing system is normal... I only have limited experience with Hurricane Electric and Equinix before. Wondering if Verizon or Comcast is also broken like AT&T. Here are the issues I had with their system: - Clicking random links around the portal will give you HTTP 400 errors, sometimes. - I'm unable to add payment methods even after following the payment tutorial exactly. The portal consistently gives HTTP 413 errors. - Live chat doesn't work at all. Clicking the button returns HTTP 404 in my debugging console. - Extremely slow for some tasks which may result in a HTTP 408. The system feels like a collection of HTTP error codes... How can it be so broken? Are other ISP's internal billing systems broken like this? Looking for anecdotes / experiences. Azayaka

Re: Low to Mid Range DWDM Platforms
by Thomas Croghan 09 Oct '23

09 Oct '23

I did some work with their passive DWDM equipment. Everything was within spec and seemed to work fine for the year I was there after we deployed it. Actually being honest, we did all our light loss math based on FS's specs and we ended up having to use attenuators in one instance. So be certain to check the certification sheets when you get your product.

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes.

Using RFC1918 on Global table as Loopbacks
by Javier Gutierrez 06 Oct '23

06 Oct '23

Hi, I have recently encountered some operational differences at my new organization that are not what I have been exposed to before, where the loopback of the core network devices is being set from RFC1918 while on the global routing table. I'm sure this is not a major issue but I have mostly seen that ISPs use global IPs for loopbacks on devices that would and hold global routing. My question is, what is the most used or recommended way to do this, if I continue to use RFC1918 I will save some very much desired public address space, but would this come back to bite me in the future? Kind regards, Javier Gutierrez,

APRICOT 2024: Call for Programme Committee Volunteers
by Mark Tinka 06 Oct '23

06 Oct '23

Hi everyone. The APRICOT 2024 Organising Committee would like to welcome everyone to join us in Bangkok, Thailand, from 21st February to 1st March 2024. The APRICOT 2024 Programme Committee is responsible for the solicitation and selection of suitable presentation and tutorial content for the APRICOT 2024 conference (https://2024.apricot.net/) We are now seeking nominations from the community to join the APRICOT 2024 PC to assist with the development of the programme for APRICOT 2024. Eligible PC candidates must have attended recent APRICOT events, have broad technical knowledge of Internet operations, and have good familiarity with the format of APRICOT. Having constructive opinions and ideas about how the programme content might be improved is of high value too. PC members are expected to work actively to solicit content and review submissions for technical merit. The PC meets by conference call, weekly in frequency during the three months prior to APRICOT. If you are interested in joining the PC and meet the above eligibility criteria, please send a brief note to "pc-chairs at apricot.net". The note must include affiliation (if any) and a brief description about why you would make a good addition to the PC. The PC Chairs will accept nominations received by 17:00 UTC+8 on Friday 20th October 2023, and will announce the new PC shortly thereafter. Many thanks! Mark Tinka & Mark Duffell For the APRICOT 2024 Organising Committee --

Re: maximum ipv4 bgp prefix length of /24 ?
by Jakob Heitz (jheitz) 05 Oct '23

Each unit of mask length increase doubles the size of the table theoretically. About 60% of the table is /24 routes. Just going to /25 will probably double the table size. Not sure I'd like to extrapolate the estimate out to /27. Kind Regards, Jakob ----------------------------------------------------------------------------- Date: Fri, 29 Sep 2023 00:25:55 +0300 From: VOLKAN SAL?H <volkan.salih.06(a)gmail.com> To: nanog(a)nanog.org hello, I believe, ISPs should also allow ipv4 prefixes with length between /25-/27 instead of limiting maximum length to /24.. I also believe that RIRs and LIRs should allocate /27s which has 32 IPv4 address. considering IPv4 world is now mostly NAT'ed, 32 IPv4s are sufficient for most of the small and medium sized organizations and also home office workers like youtubers, and professional gamers and webmasters! It is because BGP research and experiment networks can not get /24 due to high IPv4 prices, but they have to get an IPv4 prefix to learn BGP in IPv4 world. What do you think about this? What could be done here? Is it unacceptable; considering most big networks that do full-table-routing also use multi-core routers with lots of RAM? those would probably handle /27s and while small networks mostly use default routing, it should be reasonable to allow /25-/27? Thanks for reading, regards..
