boostrapcdn.com not reliable

Hi,
I'm developing with the demo and I sometimes have https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js or/and https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css which can't be loaded.
Should those files be present in source code to avoid this behavior?

Hmm, surprising, it looks like it's an error with the certificate. If it happens too often then yes we can definitely put them in the source, the two files amount to around 200KB together.

Yes it is strange as it works most part of the time.
When looking at https://www.bootstrapcdn.com/ it seems https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/css/bootstrap.min.css is preferred.
