Also experiencing this issue. Glad I checked the forum and that's it not just me. I even tried multiple browsers thinking it was perhaps a browser specific issue. Hoping the issue will be resolved soon.
UPDATE: And everything seems to be back up now. Thanks so much to the Laracasts team! I don't even recall the last time I had an issue on this site and I've been a subscriber for years. Certainly a testament to how great the team is to keep things running so smoothly overall!
