Reproduction Steps

The v2 source code for comparison

import AWS from "aws-sdk";
const client = new AWS.S3({ logger: console });
try {
  await client.listBuckets().promise();
} catch (error) {}

Disable the network, and run the test code. In the output, you can see that three retries were made

[AWS s3 undefined 0.25s 3 retries] listBuckets({})

An equivalent code in v3

import { S3 } from "@aws-sdk/client-s3";
const client = new S3();
await client.listBuckets();

Observed Behavior

When run after disabling the network, the $metadata indicates retry attempts were not made

node:internal/modules/run_main:129
    triggerUncaughtException(
    ^

Error: getaddrinfo ENOTFOUND s3.us-west-2.amazonaws.com
    at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:120:26) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 's3.us-west-2.amazonaws.com',
  '$metadata': { attempts: 1, totalRetryDelay: 0 }
}

Expected Behavior

The error should still be thrown since network is disabled, but after four attempts (three retries) as follows

node:internal/modules/run_main:129
    triggerUncaughtException(
    ^

Error: getaddrinfo ENOTFOUND s3.us-west-2.amazonaws.com
    at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:120:26) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 's3.us-west-2.amazonaws.com',
  '$metadata': { attempts: 4, totalRetryDelay: 357 }
}

Possible Solution

Process ENOTFOUND from Node.js as a retryable error?

Additional Information/Context

The internal specification for retries says

A response can be retryable based on various attributes:

Connection errors, defined as any error received by the SDK in which we were unable to receive an HTTP response from the service.
