Goodbye, ipSpace.net Subscription

I ran the first webinar as an independent author almost exactly fourteen years ago1, with the first ticket sold just before New Year’s Eve. I kept focusing on individual webinars until someone asked me, “Would it be possible to buy access to everything you did?” His question effectively created the ipSpace.net subscription, with the first one sold in late 2010 (I still have the email that triggered the whole process).

Since then, the materials kept accumulating, and as of late 2023, the ipSpace.net subscription included almost 90 webinars with over 1800 videos for a total length of over 400 hours.

Unfortunately, the second law of thermodynamics remains as ruthless as ever, and all things eventually come to an end – it’s no longer possible to buy an ipSpace.net subscription2. If you had an active subscription on January 1st, 2024, I extended it for another 75 years; if you did not, you missed it.

Finally, I would like to thank everyone who ever bought a subscription. Without you, there would have been no ipSpace.net content. You enabled me to create everything I already mentioned and all the free stuff (including over 4000 blog posts) that other networking nerds kept reading for years. I guess they should thank you profusely, but we all know how the Internet works 🤷‍♂️ From my end, I’m forever grateful to everyone who trusted me.

Last but definitely not least, it looks like you won’t get rid of me3. I will write an occasional blog post, I already have ideas for virtual labs covering other technologies (not just BGP), and I’ll keep improving the tool that makes those labs possible.

  1. I found the following info on your website and I wonder if you still consider to update these webminars:

    SDN-Related Technologies Winter 2024 Explore TCP, HTTP and QUIC Spring 2024 Explore Virtual Data Center Networking Infrastructure Spring 2024 Explore VMware NSX-T Update Spring 2024

  2. It's sad for me to see this part retiring. I've been always postponing this and then when I've finally decided to go somewhere along the direction of CCDE and thought of your Sub - it's no longer there :'(

    Still, I'd like to ask you the same question: "Would it be possible to buy access to everything you did?". I understand that it won't be maintained in the foreseeable future (or ever), but I'm pretty sure there're folks (like me) who're fine paying a one-time fee for that (or donating to your favorite charity, or another option).

    1. Agree, I hope it become accessible again for one time fee or regular subscription whichever works

  3. This hits hard. I had a basic sub that lapse, then I was unemployed, finally when I had some $ to allocate to pro. development I read this.
