Backlash to data centers prompts political upset in northern Virginia By MATTHEW BARAKAT https://apnews.com/article/virginia-election-data-centers-prince-william-22… FALLS CHURCH, Va. (AP) — The tech industry’s drive to dot the Virginia landscape with data centers may have hit a glitch this week in Prince William County. [...] The plan, called the Prince William Digital Gateway, prompted one of the region’s biggest land-use disputes in decades. It was approved despite vocal opposition from residents concerned that the data centers are noisy, ugly, and consume massive amounts of electricity that require the addition of high-voltage transmission lines. [...] Josh Levi, president of the Data Center Coalition, an industry trade group, said that data centers can make a compelling argument to local officials about the tax benefits that accrue from hosting data centers. “The industry prioritizes maintaining an open, active, and collaborative dialogue with elected officials and candidates for office, their constituents, and other community stakeholders,” he said in a statement.

Help Us Measure Fixed 5G Networks
by Nick Feamster 28 Jun '23

28 Jun '23

Hello, We are working on a project to measure the performance of Fixed 5G wireless networks. If you or anyone you know are a subscriber of: * Starlink * Verizon * T-Mobile you are eligible to help us with this study. Participation is simple: We send a Raspberry Pi with some pre-installed measurement software (Netrics), you plug it into the wall and your cable modem, and we give you a performance dashboard with your network performance, including comparisons to other networks. We offer a small participation incentive, as well. We’d ask for participation for 1-2 months, although you are welcome to continue your participation longer. See the form below for more information, including how to participate: https://uchicago.co1.qualtrics.com/jfe/form/SV_eCFrZhRhNphkVGm Thanks, Nick Feamster and Francesco Bronzino

Equinix MLPE max-prefix 0?
by Phillip Crescent 27 Jun '23

27 Jun '23

It seem overnight equinix set the mlpe router server max prefix value to 0 for their 24115 ASN. This is the ASN used for all router server sessions https://www.peeringdb.com/net/3658 I’m not clear on why an IX would do this… anyone?

ATT Wireless 2nd tier Tech support?
by Robert Taylor 26 Jun '23

26 Jun '23

I know this is the wrong place to ask, but I have some users that are having some odd issues trying to a certain number(it's a dr office at a hospital) on their cell phone when on AT&T. I have had multiple people try the same number(including myself) and it does not work. Same number works from a land line with no issues. Someone from outside the area could call the number with no issues as well, so the problem might be somewhat localized. Not sure if the issue is on the AT&T side or the recipient side. Can someone point me in the right direction? Thanks. rgt

Is there a fundamental physics problem or are they all designed for industrial areas where the noise isn't much of a problem? If I wanted a less noisy one, could I get it? How much more would it cost? Are the zoning people smart enough to include noise limits? ... -- These are my opinions. I hate spam.

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. Regards, Robert P.S. Apologies to anyone receiving multiple copies of this announcement. -- Robert Story USC Information Sciences Institute <http://www.isi.edu/> Networking and Cybersecurity Division
