What doesn't travel is how it gets written down. Every vendor and orchestrator has its own dialect, and most automation tools still push device-specific config from an orchestrator down to all involved devices. Translation, not domain-specific problems, becomes a bottleneck.\r\n\r\nWe build _Wire-API_ with a different model in mind: Instead of targeting devices, operators declare the state they want and controllers work out which devices are affected and what config to push. In the case of an EVPN fabric for example: describe it with objects like `Network`, `RoutingDomain`, and `ExternalConnection`, and adding a network becomes one object rather than a coordinated change across every leaf and firewall that participates. The shift is in what gets declared: desired state instead of a device's running config. From there, drift correction and HA-aware maintenance stop being separate runbooks and become properties of the reconcile loop, and the same model extends to anything else on the network expressed as intent.\r\n\r\nThe core is Kubernetes. _Wire-API_ is a set of CRDs and controllers that reuse the contract that made Kubernetes work in \"compute\"\u2014declared state, continuous reconciliation, honest status\u2014and apply it to the network domain.\r\n\r\nThe presentation argues for the _Wire-API_ model and walks through a live EVPN-VXLAN example\u2014one intent object, vendor-specific config on Cisco NX-OS and Nokia SR Linux\u2014then covers design decisions and partial-failure handling.

Announce the same IP address from multiple locations, allow BGP to choose a path, and traffic should reach the \"nearest\" instance, although BGP's idea of nearest often has little to do with geography.\r\n\r\nProVision (formerly 6connect) operates an anycast DNS platform spanning six prefixes, 39 BGP nodes, 13 regions, and five continents. For years, we knew the platform worked because queries were answered. What we could not prove was how it worked: which users reached which nodes, how quickly packets arrived, and where traffic quietly disappeared.\r\n\r\nThis presentation tells the story of how we turned one of anycast's most frustrating behaviors-ICMP replies returning to the \"wrong\" node-into a measurement. That insight grew into an automated pipeline running 117,000 probes per second across 2.6 million targets, measuring latency, loss, jitter, routing behavior, path MTU failures, ECMP paths, and visibility at 845 Internet Exchanges.\r\n\r\nIt is also the story of how two network engineers who are not full-time developers built the system through intensive collaboration with AI coding models. AI supplied much of the implementation capacity; the humans supplied decades of network intuition, architectural direction, validation, and the authority to say when the code was confidently wrong.", "description": "Anycast underpins critical Internet services, including DNS, content delivery networks, and DDoS mitigation platforms. The model appears simple: announce the same IP address from multiple locations and allow BGP to direct traffic toward the best available path, but the operational reality is far less transparent.\r\n\r\nProVision (formerly 6connect operates an anycast DNS platform built around six prefixes announced by 39 BGP nodes in 13 regions across five continents. The platform answered queries reliably, yet ordinary service monitoring could reveal only part of the story. It could tell us that a DNS request succeeded, but not always which node handled it, whether BGP selected the node we expected, how latency differed across the catchment, or where packets were being lost without causing a visible outage.\r\n\r\nMeasuring the network from inside the platform created a chicken-and-egg problem. Anycast is designed to make many distributed instances appear to be one destination, so the topology we wanted to study was the same topology the service was designed to conceal. We could not simply ask the Internet which node it would reach. We needed a way to make the network reveal its own routing decisions.\r\n\r\nThe breakthrough came from a behavior that initially appeared to undermine the measurements. We sent probes from the production anycast source addresses and observed that ICMP errors frequently returned to the \"wrong\" node rather than the node that originated the probe. That wrong node was the answer.\r\n\r\nThe node receiving the ICMP response was the node BGP had selected as the return path for the router generating it. By recording those responses across the network, we could begin mapping real anycast catchments from the perspective of the infrastructure itself. The apparent flaw became the core measurement primitive. From that insight, we built a fully automated daily measurement pipeline capable of:\r\n\r\nRunning 117,000 probes per second across 2.6 million targets Measuring round-trip time, packet loss, and jitter for 1.4 million addresses Detecting path MTU discovery black holes Performing ECMP-aware traceroutes Correlating active measurements with BGP monitoring Measuring platform visibility at 845 Internet Exchanges\r\n\r\nAttendees will leave with a practical understanding of why anycast is so difficult to measure, how asymmetric ICMP routing can reveal real BGP catchments, and what it takes to turn that observation into a large-scale monitoring system.

This one isn't. If you operate an ISP, a hosting platform, a cloud, or a registrar, you are the *addressee* of these orders \u2014 and the obligations are technical and time-boxed long before they're legal.\r\n\r\nWe'll start with the 90-second operator edition: European Production Orders (EPOC) and European Preservation Orders (EPOC-PR), who can issue them, which data categories are in play (subscriber, traffic, content), and the deadlines that turn this into an on-call problem rather than a policy memo. Then we get to the parts nobody warns you about: that you must designate an establishment or legal representative, that liability is joint and several with fines reaching into a percentage of global turnover, and that there's an actual machine interface behind all this \u2014 a decentralised IT system, a transport spec, a hard size limit, and a rollout that may not be finished when the orders start arriving.\r\n\r\nThe practical core is simpler than the crypto-heavy forensics literature suggests. Evidence just needs to be trustworthy: the right data, demonstrably unchanged, anchored in time, and traceable back to where it came from. You don't need a forensics lab for that \u2014 you need to know whether the logs and exports you already produce would survive someone asking \"how do you know this is genuine?\" We'll cover the idea at a level you can act on, then look at how it usually falls apart in practice: data that's already been rotated away, mutable logs, a screenshot instead of a record, no idea who pulled what or when.\r\n\r\nWe close with a field report from the first months of the regime \u2014 readiness across the EU, what early orders actually look like, and a pragmatic checklist so that when (not if) one lands in your inbox, you can produce the right data, in a defensible form, within the deadline \u2014 without it turning into a fire drill every time.\r\n\r\nThis session is for ISP, hosting, cloud, and registrar engineers, DevOps, abuse/LI-interface teams, and anyone who owns logging or will be the one woken up at 2 a.m. by an 8-hour emergency order.
