So we’ve done this now:

# fly.toml file generated for pdp-preview-db on 2023-01-18T10:53:32-05:00

app = "pdp-preview-db"
kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[env]

[experimental]
  auto_rollback = true

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []
  [services.concurrency]
    hard_limit = 100
    soft_limit = 75
    type = "connections"

  [[services.ports]]
    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

? This feature is highly experimental and may produce unexpected results. Proceed? Yes

But the result is that concurrency is NOT updated. Why?

❯ f config show -a pdp-preview-db
