Sinch Status FAQ

Is Sinch down right now?

PulsAPI checks Sinch every 60 seconds. The verdict at the top of this page comes from the latest poll of the official Sinch status feed and refreshes automatically, so you are not looking at a stale cached answer.

What should I do if Sinch is not working?

Check the component list on this page first to see if your failure matches a known outage. If it does, you can report the issue for other engineers, follow the incident timeline for vendor updates, and run any fallback your app supports until Sinch recovers.

How do I check Sinch uptime history?

PulsAPI tracks Sinch uptime over 30, 60, and 90-day rolling windows. The current 30-day uptime is 99.87%. A free PulsAPI account unlocks the full 90-day SLA history and incident timeline for Sinch.

How fast does PulsAPI detect Sinch outages?

PulsAPI polls the official Sinch status page every 60 seconds and usually delivers alerts to Slack, Discord, Microsoft Teams, PagerDuty, or email in under 4 seconds after detection. That is often faster than someone on your team notices on their own.
