Anyone ever had to deal with etsy.com returning 429 for all subnets? We have very little traffic going to etsy at any given moment but every prefix we have returns a 429 Too Many Requests error when trying to get to etsy.com . Regards, Josh

L4S Trials (Comcast) & Inter-Domain Marking
by Livingood, Jason 22 Jun '23

22 Jun '23

FYI on two related items of interest to this list. 1 – If you are a Comcast customer, consider volunteering for our upcoming low latency networking trials (using IETF L4S). See my blog post at https://corporate.comcast.com/stories/comcast-kicks-off-industrys-first-low… and signup at https://www.xfinityinsightscommunity.com/register/start/f4f1ea42-247c-44f1-…. 2 – The IETF L4S standard and the upcoming NQB standards – both dual-queue low latency networking – will rely on end-to-end packet marking to signal dual-queue-capable routers to send packets to the low latency queue. Thus, there will be inter-domain marking which will affect many networks’ edge configurations. * In the case of L4S it may be easier, as L4S relies on the ECN header – and most networks probably forward packets without touching this header. The L4S setting here is to set ECT(1) or CE. * In the case of NQB, the marking is expected to use DSCP-45 (once the RFCs are issued, IANA will make the code point assignment). This will be more challenging for those networks that scrub any DSCP marks from packets and over-write with their own. Post-standardization, networks should permit inbound DSCP-45 marks to remain & pass them along down to the user edge (in cases where 45 is used internally, networks may remark internally and then mark back to 45 as it goes to the user LAN). * In both cases – ECN or DSCP – the packets remain at the best effort priority level. * For slightly more detail see https://github.com/jlivingood/IETF-L4S-Deployment/blob/main/Network-Config-… Thanks!

New addresses for b.root-servers.net
by Robert Story 21 Jun '23

21 Jun '23

USC/ISI is renumbering both its IPv4 and IPv6 addresses for b.root-servers.net on 2023-11-27. Our new IPv4 address will be 170.247.170.2 and our new IPv6 address will be 2801:1b8:10::b. USC/ISI will continue to support root service over our current IPv4 and IPv6 addresses for at least one year (until 2024-11-27) in order to provide a stable transition period while new root hints files are distributed in software and operating system packages. We are renumbering to increase the resilience of the Root Servers System by further diversifying the number of Regional Internet Registries (RIRs) that have allocated IP addresses to Root Server Operators. Our addresses will be the first in the Root Server System to have been allocated by LACNIC and our routes will be verifiable through LACNIC’s Resource Public Key Infrastructure (RPKI) Trust Anchor Location (TAL). We thank LACNIC for helping make this renumbering possible, and ARIN for supporting our prior addressing assignments. The LACNIC announcement, with English, Spanish and Portuguese translations, can be found on their website here: https://www.lacnic.net/6868/1/lacnic/lacnic-asigna-recursos-de-numeracion-a… Please direct any comments or questions to b-poc <at> isi.edu.

FCC Chair Rosenworcel Proposes to Investigate Impact of Data Caps
by Sean Donelan 20 Jun '23

20 Jun '23

While a lot of ISPs gave up on data caps, the language is still lurking in many Terms Of Service. https://www.fcc.gov/document/chair-rosenworcel-proposes-investigate-impact-… proposed Notice of Inquiry to learn more about how broadband providers use data caps on consumer plans. Data caps, or usage limits, are a common practice where an internet service provider (ISP) restricts how much bandwidth or data a consumer uses, though many broadband ISPs temporarily or permanently refrained from enforcing or imposing data caps in response to the COVID-19 pandemic. In particular, the agency would like to better understand the current state of data caps, their impact on consumers, and whether the Commission should consider taking action to ensure that data caps do not cause harm to competition or consumers’ ability to access broadband Internet services.

That's been the general theme with operators who are traditionally Layer 1 or Layer 2 service providers, looking to dabble into packet switching. It often makes sense for them to speak to their Transport vendor, as their gear is already an installed base. Two or so years later, those operators will be ripping those Transport boxes out and replacing them with more traditional packet switching gear, as you did as well. Transport vendors continue to push their boxes as being MPLS-capable routers. It tends to be a "tick the box that we had that conversation this new year, make it last at least 3 seconds, and then carry on with real talk" situation :-). Mark.

10G CPE w/VXLAN - vendors?
by Adam Thompson 16 Jun '23

16 Jun '23

Hello, all. I’m having difficulty finding vendors, never mind products, that fit my need. We have a small but growing number of L2 (bridged) customers that have diverse fiber paths available, and, naturally, want to make use of them. We have a solution for this: we extend the edge of our EVPN VXLAN fabric right to the customer premise. The customer-prem device needs 4x10G SFP+ cages (2 redundant paths, plus LAG to customer), and the switches we currently use, Arista 7020Rs, are quite expensive if I’m deploying one one per customer. (Nice switches, but overkill here – I don’t need 40/100G, and I don’t need 24 SFP+ ports. And they still take forever to ship.) We use RFC7438 §6.3 “vlan-aware-bundle” mode, not §6.1 “vlan-based” mode, which limits our choices somewhat. I might be willing to entertain spinning up a separate VXLAN mesh using RFC7438 §6.1 (“vlan-based”) and static VTEPs if it saves me a lot of pain. However, I’m having trouble finding small & cheaper 1U (or even desktop/wallmount) devices that have 4 SFP+ cages, and can do VXLAN, in the first place. Who even makes CPE gear with SFP+ ports? (Other than Mikrotik CRS309-1G-8S+IN / CRS317-1G-16S+RM, which are nice, but our policy requires vendor support contracts, so… no-go.) Vendors? Model#s, if you happen to know any? Reply here or privately, whatever floats your boat – any pointers appreciated!
