SWA auth middleware randomly crash

I encounter a big issue right now.
I have 4 static web apps deployed on azure (Central France datacenter) and they all break at the same time. More specifically the Auth middleware from the static web app seems to be broken for ~3min every 10min. During this downtime, all auth routes (eg: `/.auth/*`) are not redirecting following `staticwebapp.config.json` configuration.
As result, all these routes are handled by my Nuxt.js app and fallback to a 404 error.

*Additionnal informations:*

- each SWA is deployed on independant resource group
- this behavior started since 1/25/23
- I never had similar issue before this date
