Newly deployed instances are not responding. Looks like a DNS issue.

Deploying [this code](https://github.com/scale-tone/cognitive-search-static-web-apps-sample-ui) to a newly created Static Web App instance. Tried deploying via both Azure Portal and CLI. Results are the same: the instance is created, the deployment workflow succeeds, the instance looks healthy in the portal, but the app's root URL does not respond (fails with ERR_CONNECTION_TIMEOUT):


Tried two regions: centralus and westeurope. No difference.

nslookup on the newly created DNS name (nice-wave-04a90fd10.1.azurestaticapps.net) looks weird:
```
C:\projects\github\cognitive-search-static-web-apps-sample-ui>nslookup nice-wave-04a90fd10.1.azurestaticapps.net
Server: sahhgw.home
Address: 10.0.0.138

Non-authoritative answer:
Name: nettvern-info.telenor.net
Address: 148.123.15.44
Aliases: nice-wave-04a90fd10.1.azurestaticapps.net
```

Compare this with result for my previously created, healthy instance:
```
C:\projects\github\cognitive-search-static-web-apps-sample-ui>nslookup lively-sand-033e9ec03.azurestaticapps.net
Server: sahhgw.home
Address: 10.0.0.138

Non-authoritative answer:
Name: waws-prod-am2-0ab44d07.cloudapp.net
Address: 40.118.40.109
Aliases: lively-sand-033e9ec03.azurestaticapps.net
azurestaticapps.trafficmanager.net
msha-am2-0.staticsites-prod-westeurope.p.azurewebsites.net
waws-prod-am2-0ab44d07.sip.p.azurewebsites.windows.net
```

Doing nslookup nice-wave-04a90fd10.1.azurestaticapps.net from a GitHub codespace produces different results:

```
@scale-tone ➜ /workspaces/az-messaging-demo (main ✗) $ nslookup nice-wave-04a90fd10.1.azurestaticapps.net
Server: 127.0.0.53
Address: 127.0.0.53#53

Non-authoritative answer:
nice-wave-04a90fd10.1.azurestaticapps.net canonical name = azurestaticapps1.trafficmanager.net.
azurestaticapps1.trafficmanager.net canonical name = msha-slice-1-am2-1.msha-slice-1-am2-1-ase.p.azurewebsites.net.
msha-slice-1-am2-1.msha-slice-1-am2-1-ase.p.azurewebsites.net canonical name = waws-prod-am2-8b19502a.sip.p.azurewebsites.windows.net.
Name: waws-prod-am2-8b19502a.sip.p.azurewebsites.windows.net
Address: 51.124.12.35
```

Requesting that '51.124.12.35' address results in 404:

[Deployment workflow is here](https://github.com/scale-tone/cognitive-search-static-web-apps-sample-ui/blob/master/.github/workflows/azure-static-web-apps-nice-wave-04a90fd10.yml).

**To Reproduce**

- Try to navigate to the app's root page.
