Looking at our CDN stats, I only see 10 5XX errors total in the past week, so I don't think it's an availability issue. Lots of things can cause fetch errors, such as browser extensions and networking issues.

Hmm. Ok. I'm betting the problem is on the package I'm using. I will change it to use pure Growthbook SDK. I saw something about "fetch" on my automated tests, leading me to do an unusual approach. The more I explain, more visible is the trouble for me, hahahah.
