The new AI Model Hub and vGPU services announced at yesterday's @IONOS Summit are exactly what enterprises need right now. But a powerful AI model isn't very useful if it takes months to provision the network connection to it. Enter the @DE-CIX Cloud and AI Exchanges. We offer hundreds of gigabits of capacity for direct, private connectivity to your business-critical AI workloads. You handle the AI models; we handle the plumbing. And thanks to our automation, you can establish those secure connections in seconds.

Every massive engineering project starts with a single, innocent ticket. In our case, it was: "Vendor announced end-of-life for a software component." What started as a simple replacement quickly escalated into a complete modernization of our network automation stack to fully support our NaaS vision. Meet NORC. Now, customer changes hit the network in seconds. Product teams define the business intent, and NORC handles the technical translation. We can roll out new features in hours instead of weeks, backed by test coverage so high that deployments are actually fun. Migrating a global network is not for the faint of heart, but the @DE-CIX engineering team executed it flawlessly. The migration for our customers included only a single small maintenance window, which is the highest compliment you can give in network engineering 😉

Setting up point-to-point connectivity between two ports you actually own is easy. Connecting to a third-party cloud or Anti-DDoS provider? That usually involves a painful administrative request-accept dance and manually translating VLAN IDs. To save our enterprise customers from this specific networking headache, we have fully automated the entire process directly in the @DE-CIX Portal and API. You can now spin up third-party interconnections across our global network instantly and on-demand. Let the system do the translating so your engineers don't have to 😉 docs.de-cix.net/article/chom…

Careers in tech rarely follow a static, pre-configured route. Much like a dynamic network, they are shaped by discovering new paths, adapting to changes, and staying relentlessly curious. This morning, I joined an interactive discussion with the students at @HTL Mössingerstraße in Klagenfurt, alongside alumni @Marco Brandstätter and @Alexander Windbichler. What started as a standard talk about technology quickly turned into a sharp discussion about career choices and navigating an industry that never stands still. Speaking with the next generation of engineers is always a great reality check. They ask the unexpected questions that those of us deep in the industry sometimes forget to ask. Thank you to everyone involved for a highly refreshing exchange 🚀

While most people spend their lives trying to avoid traffic, I actively celebrate it. Hitting a new peak at one of our exchanges is the ultimate proof that our customers trust us with the exact thing their own users depend on 100%. Today, we hit an absolute milestone: @DE-CIX Frankfurt just reached 20 Tbps for the first time ever! Thank you to our customers for your continued trust (and your data), and absolute kudos to the team for making this historic scale a reality. Let's see how quickly we can fill the next terabit 😉 de-cix.net/en/locations/fran…

There are roughly as many reasons to choose a specific cloud provider as there are workloads to run on them. Our job isn't to ask why; it's to make the interconnection as flawless as possible. We are continuously expanding our ecosystem so our customers never hit a dead end. That is why I am happy to share that IONOS and Alibaba Cloud are now fully supported across @DE-CIX DirectCLOUD and Cloud ROUTER. Connecting your critical workloads just got a little bit easier today. de-cix.net/en/services/direc…

Cloud providers reusing AS numbers across regions is one of those industry quirks that keeps network engineers awake at night. To help you sleep a little better, we just rolled out the AS Override feature globally on the DE-CIX Cloud ROUTER. It removes the friction for complex, multi-national enterprise connectivity. The early feedback has been fantastic, but I'd love to hear how it works for your specific setups. You can find all the technical details right here: docs.de-cix.net/article/nlkh…

Some people drink espresso to get their heart rate up; I just look at our bandwidth charts. Every time we hit a new traffic peak, it is the ultimate proof that our customers trust the infrastructure we are building. That is why I am absolutely thrilled to announce that DE-CIX Chicago has officially crossed the magic 1 Terabit threshold! Chicago is now the seventh of our Internet Exchanges to join the 1Terabit Club. Massive congratulations to the team for keeping the infrastructure rock solid, and a huge thank you to our customers for keeping the pipes so incredibly busy 🚀 de-cix.net/en/locations/chic…

Patience might be a virtue, but definitely not when you are waiting for network configurations to provision. If you are buying Network as a Service, you expect it to behave exactly like the cloud: instant. The @DE-CIX DirectCLOUD and Cloud ROUTER product teams just gave the @DE-CIX automation toolchain a serious upgrade. Configuration changes via our portal or API now hit the network in under 5 seconds. We used to measure this in minutes. Now, your new cloud connectivity is live before you can even finish pulling a decent shot of espresso ☕ Excellent work by the team. I hope our customers enjoy the new speed!
