# Coralogix endpoint updates and deprecations

Coralogix continuously improves its regional endpoint architecture to deliver higher reliability, improved performance, and consistent ingestion behavior across all observability sources. This page provides a complete view of new endpoints, changes, active deprecations, and required migration actions.

Use this page alongside the main [Coralogix Endpoints](https://coralogix.com/docs/integrations/coralogix-endpoints/index.md) page to ensure your integrations always point to the correct, supported endpoints for your region.

## Latest updates

### Deprecation of legacy log ingestion endpoints

As part of our long-term platform modernization effort, Coralogix will permanently deprecate legacy data ingestion endpoints on April 30, 2026.

These endpoints were originally built around a single global load balancer. Over the past three years, we’ve transitioned to region-specific endpoints and infrastructure to improve availability, observability, and security.

**Action is required** to ensure uninterrupted log ingestion.

See full details on the [legacy log ingestion endpoints deprecation notice](https://coralogix.com/docs/user-guides/latest-updates/deprecations/endpoints/index.md) page.

## Active deprecations

These deprecations require customer action before the effective cutoff dates.
