Load Balancing Monitor Groups: Multi-Service Health Checks for Resilient Applications

What this post added

Introduced Monitor Groups for Cloudflare Load Balancing, allowing customers to bundle multiple health monitors into a single logical entity. This feature enables defining critical monitors (`must_be_healthy`), observational probes (`monitoring_only`), and uses a quorum-based system (defaulting to >50% healthy monitors) to determine endpoint health. It also enhances Dynamic Steering by using the aggregated health score and average RTT of active monitors for traffic steering decisions. The feature is initially available via API for Enterprise customers and will be rolled out to the dashboard for all users.
