502 on maven repo / maven down?

We are facing 502 issues with maven at the moment. Are there any known issues with this URL?

Thanks for your help,

It’s back online and while I have no idea for sure what happened yet, one theory is that it is related to the Lets Encrypt root certificate expiration:

It looks like it’s down again

Seems fine to me, is it still down for you?
