Modify set of google relays

Open the file terraform/dev/relays/main.tf and change the locals section underneath "GOOGLE RELAYS" to match this:

# =============
# GOOGLE RELAYS
# =============

locals {

  google_credentials = "~/secrets/terraform-dev-relays.json"
  google_project     = file("~/secrets/dev-relays-project-id.txt")
  google_relays = {

    },

    "google.virginia.3" = {

This changes the set of google cloud relays from:

• google.iowa.1.a
• google.iowa.1.b
• google.iowa.1.c
• google.iowa.2
• google.iowa.3
• google.iowa.6
• google.ohio.1
• google.ohio.2
• google.ohio.3
• google.virginia.1
• google.virginia.2
• google.virginia.3

To:

• google.saopaulo.1
• google.saopaulo.2
• google.saopaulo.3
• google.dallas.1
• google.dallas.2
• google.dallas.3
• google.virginia.1
• google.virginia.2
• google.virginia.3
• google.southcarolina.2
• google.southcarolina.3
• google.southcarolina.4

The good news is that terraform takes care of all changes for you, including removing old google cloud VMs and adding new ones. It's all automatic.

First check in your work:

git commit -am "change google relays"
git push origin

Then run terraform:

cd terraform/dev/relays
terraform apply

Commit the database to the backend to make it active:

cd ~/next
next database
next commit

Wait a few minutes for the relays to initialize...

Connect to the VPN, then setup the new google relays:

next setup google

After about 5 minutes the new relays should be online:

next relays

Now we can SSH into the test server again:

Then run:

sudo systemctl restart app && sudo journalctl -fu app

and you'll see that the test server now finds a server relay in Sao Paulo:

This is great news. Acceleration is now possible.

But to actually find this acceleration, we need multiple different networks to optimize across for clients connecting to google.saopaulo.1

This means we need to spin up as many different relays in Sao Paulo that we can find from different hosting companies!
