Last month @iznaut brought to attention that the live feed of the Centennial Bulb was unavailable. In this post I figured out that the livestream from the original website stopped updating since August, and thought that the camera stopped working. @nicky confirmed that the bulb was still alive.
In a recent article about the bulb, the author mentions a 'Bulbcam' which links to a new website, separate from the original one. This website has a functional live feed. It looks like the camera was changed too.

Hooray!
