David you're probably just getting nonstop flak for this and as the CEO of the "big bad" here just let me say that I feel genuinely bad for you. Whatever conversation you have to have behind the scenes is a truly stupid thing to have to do in this situation. The CDN thing is dumb and maybe arguably not how this should have been done but your team and their work doesn't deserve to be villified for doing basically nothing wrong other than a very simple email miscommunication.

Good luck with this all.
