Resolved
Should be solved by now. Thank you for your patience and sorry for the problems!
Monitoring
Everything should work back now, and the progress should be back. I will monitor the pages just in case,
Identified
I'm now changing the DNS configuration and GitHub Pages configuration to restore saves and status of the original pages.
Investigating
I have good news and bad news.
The good ones are that now we have a custom domain! (jaime-gaming.com)
The bad ones are that i've lost all GitHub Pages. I'm trying to recover them while deploying the new domain ones.
