I tried adding a TOC / Video Timeline to the YouTube video but unable to.

I unfortunately don't have access to the heptio youtube account anymore. My permissions got lost during all of the account transitions. I'll try and chased this down.

Thanks for getting back. I was able to finally add it by split it into 2 shorter messages that did not hit some limit I wasn't aware of.

That video is really awesome and I always share the link when someone asks about certificate expiry.
