Speculus - Threat intelligence feed outage

Description

'Detects when no Speculus threat intelligence indicators have been received for more than 24 hours. The Speculus indexer refreshes continuously, so a silent day usually means an expired API key, a connector misconfiguration, or a feed-side outage rather than an empty feed.'
