Are the glitch projects down?

I haven’t been to the glitch projects yet and I have just finished the first 2 courses. However I have stumbled through the next few ones and I found out I could not get to see any glitch project up and running, for example
Are all these down or is there a chance that I need to finish all lessons before this is unlocked?
Thank you for your clearance.

Hello there,

Most, if not all, of the example projects are down. We are aware of this, and are working to get this resolved, but it is most likely caused by the account running out of CPU time with Glitch. There is nothing for you to unlock.

Hope this clarifies.

Thank you! I understand the situation now.
