I'm running the e2e tests with this branch, if that looks good I will merge it.

[johnbelamaric]

Ok, I haven't tested the actual connectivity over those networks, but at least it doesn't break the e2e, so I will merge it. If connectivity is an issue we will find it and tweak it later, but I doubt there will be an issue. Thanks!

Why though is there no edge01 node? Can you look into that @electrocucaracha and submit a follow-up PR?

I think that we have to improve the waiting process. I noticed the edge clusters don't come alive
