The affected host, elastic1043, is due to be replaced soon per https://phabricator.wikimedia.org/T279158. Rather than file a proper hardware failure with dc-ops, I'm just using this ticket as a placeholder so I have something to ack the alerts with.

I can't find much useful from the system event logs (https://wikitech.wikimedia.org/wiki/SRE/Dc-operations/Platform-specific_documentation/HP_Documentation#Show_system_event_log_entries). Here's the latest entry (not recent):
```

But note that the instance is in a power off state and doesn't seem to want to turn back on:
```
