  1. investigating Jul 17, 2026, 11:48 AM UTC

    We've identified an issue affecting voice-call notifications to Singapore (+65) phone numbers. Affected customers may experience failed or missing call alerts. This is caused by a disruption at our upstream voice provider. All other notification channels (SMS, email, push, and chat) are operating normally. Incidents are still being delivered through these channels.

  2. investigating Jul 22, 2026, 02:18 PM UTC

    This incident is resolved. Voice-call notifications to Singapore (+65) numbers are delivering normally again. The disruption originated with our upstream voice provider and has since been corrected. We've verified successful call delivery and are monitoring to ensure stability. We apologize for the disruption. If you're still seeing failures, please reach out to support.
