# pub.highlight.io stops working

Calls to these calls on Highlight.io stopped working on February 28, 2026.

Highlight.io services on pub.highlight.io will stop working on February 28, 2026. The provider is deprecating services and moving its infrastructure and services to LaunchDarkly. Any calls directed to pub.highlight.io will fail after that day.

## What to use instead

Replace the Highlight SDK with LaunchDarkly Observability by initializing the LaunchDarkly SDK with a client-side ID along with the Observability and SessionReplay plugins. The move requires more than changing an identifier, as it needs a LaunchDarkly account, a new SDK key, and a LaunchDarkly plan.

Moving to LaunchDarkly Observability needs a LaunchDarkly account, a new SDK key and a LaunchDarkly plan.
