We're working to move it to a more permanent location.
Cecil and I will also be publishing a series of blog posts in the coming weeks that will go into details on the different concepts he demonstrated, including: unit testing, continuous delivery with Visual Studio Team Services, and monitoring with Application Insights.
We'll try to post updates here as these posts and other content appear.
Thanks for watching! Feel free to contact us here or on Twitter if you have questions in the meantime.
