⚠️ Merge this only ~ 3h before the switch is done and increase directly after the switch.
Lowering the TTL results in more DNS requests in Route53 and consequently higher costs.
I would reduce it when doing the switch, so in case something unexpectedly fails, we can quickly undo.

When everything works, we should not forget to merge this:

Terraform will perform the following actions:
  # aws_route53_record.usegalaxy-eu will be updated in-place
  ~ resource "aws_route53_record" "usegalaxy-eu" {
        id              = "Z1C7L7XFF9613J_usegalaxy.eu_A"
        name            = "usegalaxy.eu"
      ~ records         = [
          + "132.230.103.37",
          - "132.230.223.239",
        ]
      ~ ttl             = 7200 -> 300
        # (4 unchanged attributes hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.
