For Unbound: trust-anchor-file is static and never learns 38696 on its own. auto-trust-anchor-file does, via RFC 5011, but needs write access to the file and its directory, so check resolvers running from read-only mounts or container images.

David Huberman from ICANN shared at #ABQNOG that the DNS root KSK rollover is October 11. Running a DNSSEC-validating resolver? Confirm KSK-2024 (key tag 38696) is in your trust anchors if not, every query SERVFAILs. Not the DNS gal or guy? Pass this along! www.icann.org/resources/pa...
Everyone is obsessing over building giant gigawatt AI data centers, but the future of inference could actually be sitting inside old telecom central offices. 🏢⚡️ New blog post here: www.bitsinflight.com/ai-inference...
AI Inference Doesn't Need New Data Centers
Training does. Inference can live in buildings we already have.

Getting an education on XPO optics from Vijay Vusirikala from Arista Networks. This density is insane! #NFD40
Have heard a lot from all the vendors building networking for AI at #NFD40. Brendan from Arista Networks is doing a great job of breaking down the different architectures and the Arista differentiators.
Here we go! Tune in to see what Arista Networks is up to, we start in about 5 minutes (4/9 8a PT) #NFD40 techfieldday.com/event/nfd40/

LLMs and AI are Processing Data Telemetry Overnight 📊 🧠 Jason Gintert talks about a powerful use case for LLMs in network operations: overnight data processing. #TFDPodcast #NFD40 #Networking #LLMs #DataTelemetry #DataProcessing #NetworkData
It's interesting how @nokia.bsky.social is positioning their validated design guides as a product that gets a support life and that gets yearly updates. That's a far cry from many vendors that create a validated design and then ignore it for a decade. #nfd40
Guess who is in San Jose for #NFD40? This guy ✋ See presenters and presentation times here: techfieldday.com/event/nfd40/ To stream the event live, watch here: youtube.com/@techfieldday Or at the main event page above. Use #NFD40 to ask any questions you have of the presenters. So stoked!
