Loss of external network access all of a sudden (already running container, not during deployment)

Question

I get this error for a few of the external domains we are calling from inside the container:
```
Error: getaddrinfo EAI_AGAIN discord.com

at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:107:26)

Emitted 'error' event on Client instance at:

at emitUnhandledRejectionOrErr (node:events:398:10)

at process.processTicksAndRejections (node:internal/process/task_queues:84:21) {

errno: -3001,

code: 'EAI_AGAIN',

syscall: 'getaddrinfo',

hostname: 'discord.com'

```

This happened once and crashed the container. Any ideas as to what could've happened? Metrics show a minor spike in network activity around the time it crashed but no CPU or RAM spike.
