Lattice change history: Issue with upstream provider

Lattice reported a major incident affecting email-link redirects and delaying all product notifications via email, MS Teams, or Slack because of an upstream Courier issue. It ran from 2026-02-02 21:34 UTC to 2026-02-02 22:29 UTC (54 min). Courier implemented a fix; redirects recovered and all delayed notifications were delivered, some up to one day late.
