This support reverse-DNS lookups.
I encountered a problem where I accidentally deleted my instance's
`nat_ip` (external, ephemeral IP). I needed to run...
```shell
terraform apply -replace=google_compute_instance.diogenes
```
...which invalidates terraform's local cache of the state. I believe this used
to be called `terraform taint`. Things are mostly WAI, with one known issue:
quasselcore and billandhiscomputer.com complain about missing SSL certs, but I
believe this is a race-condition. Calling...
```shell
systemctl restart quassel.service
```
...resolves the issue for quassel. Unfortunately the same doesn't work for
nginx.service, but after a bit of time https://billandhiscomputer.com "just
works". Clearly I'm not sure what's going on here. At least not yet...
