Hightouch DOES publish dated breaking-change notices in the API guide: on 2026-07-10 it removed support for four weaker TLS cipher suites (ECDHE-ECDSA-AES128-SHA256, ECDHE-RSA-AES128-SHA256, ECDHE-ECDSA-AES256-SHA384, ECDHE-RSA-AES256-SHA384) with advance notice and a client-upgrade instruction. That is a notice, not a policy, so no Deprecation pointer is emitted.' dated_notices: - date: '2026-07-10' change: Removed four weaker ECDHE SHA-2 cipher suites from the REST API source: https://hightouch.com/docs/developer-tools/api-guide sla: url: null note: Custom SLAs are listed as a Composable CDP plan feature on https://hightouch.com/pricing; no public uptime target is published. status_page: https://status.hightouch.io status_page_api: https://status.hightouch.io/api/v2/status.json status_page_note: Atlassian Statuspage (page id tvlyw5gy5wjb), machine-readable at /api/v2/status.json.
