Sinch Status FAQ

Is Sinch down right now?

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. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead.

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 99.99%. The 90-day uptime strip on this page is public: no account needed. A free account adds alerts whenever Sinch changes state, plus 15 days of incident detail; Pro extends that to 90 days and Business to 13 months.

How fast does PulsAPI detect Sinch outages?

PulsAPI reads the official Sinch status page. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead. Alerts reach Slack, Discord, Microsoft Teams, PagerDuty, or email within seconds of detection.

Does PulsAPI track individual Sinch components?

Yes. PulsAPI monitors 161 individual Sinch components, so you can see which service or region is affected instead of a generic "service degraded" banner.

Can I get alerts when Sinch goes down?

Yes. Create a free account and subscribe to Sinch: the free plan covers three services with unlimited email alerts and no monthly notification cap. Paid plans lift the monitor limit entirely (Pro and above do not meter how many vendors you watch) and route the same alerts into Slack, Discord, Microsoft Teams, PagerDuty and webhooks.

How do I report an issue with Sinch to the community?

Click "Report an issue" at the top of this page, pick the issue type and severity, and optionally add your region and a short note. Reports are anonymous and help other engineers spot Sinch problems early. Official status pages often lag real incidents by 10 to 20 minutes.

Is there a free way to monitor Sinch?

Yes. The free plan covers 3 monitored services with unlimited email alerts, permanently, so Sinch plus two more costs nothing. Every new account also opens with a 30-day Business trial (unlimited monitors, Slack alerts, SLA reporting) with no credit card.

Track Sinch with the rest of your stack

2463+ vendors in one dashboard, and an email the moment any of them changes state. Three free, and no monitor limit at all from $29/mo, unlike the alternatives, which keep charging by the monitor.
