I’m Wido den Hollander, a Linux and networking engineer from the Netherlands active in the internet and hosting industry since 2003. I work extensively with open-source technologies such as Apache CloudStack and Ceph.
I am passionate about IPv6, Layer 3 routing with BGP, VXLAN and EVPN. Over the years I have promoted these technologies and spoken about them at multiple conferences.
In my current role as CTO at Your.Online, I oversee the companies in our group, lead our Tech M&A activities and guide the cybersecurity strategy for the organisation.
This is my personal blog, essentially my technical notepad, where I share experiments, findings and troubleshooting notes. All content reflects my own views and is not connected to any past or present employer.
