Status
Status check unavailable
We could not reach the health endpoint from this page. That may be the API, or it may be this check - treat it as unknown rather than as an outage.
What this page does not tell you
There is no uptime percentage here, because we do not yet retain the monitoring history that would make one true. A figure invented for a status page is worth less than an honest gap, so this reports only what can be observed right now.
Where delivery problems actually show up
Most trouble with email is not the API being down. It is a domain whose DNS has lapsed, a recipient server deferring your mail, or an address on your suppression list. Those are visible in your own account rather than here: the delivery log records every event for each message, and a domain whose records stop resolving is flagged on its own page before sending is affected.
If something looks wrong and this page says everything is fine, that is worth telling us about - write to support and include a message id.
