What happened to the livecast?

Last Friday (12/15/2023) there was supposed to be a Livecast - The NOC's Role in the Cloud-first Data Center session 2

When the time for the session came, I got a 404 error trying to join, and the menu item on THWACK (Events > events > Livecasts) for live casts is no longer available. Past link's I've shared return 404's Aswell.

Anyone know if this livecast happened and if there is a recording available for it?
