Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.
What Postmark does
Postmark is a transactional email service used for the messages an application must deliver quickly: password resets, receipts and account notifications. Applications send through its API or SMTP. Its status page is deliberately simple, reporting Postmark as a single service rather than breaking it into components, and publishing scheduled infrastructure maintenance windows in advance.
What an outage looks like
Send calls fail or time out at the API or SMTP boundary, so the application learns immediately that the message did not leave. Password resets and one-time codes stop reaching users, which surfaces as a login support queue rather than as an email problem. Webhooks for delivery, bounce and open events stop arriving at your endpoint.
What to do about it
Check status.postmarkapp.com, which reports Postmark as a single service, so it will tell you whether there is an incident but not which part is affected. Your own send logs are the better diagnostic: a message that returned an error never entered Postmark and can be retried, while one that was accepted should not be re-sent. Scheduled maintenance is announced on the same page.
Is it down for everyone, or just you?

How we measure this
- We request Postmark's public endpoint every 6 hours from Fly.io regions across six continents — the most recent check ran from 8 of them.
- A region counts as down only when it gets no usable HTTP response. A
403or429means the origin answered and refused us, which we report as blocked, never as an outage. - A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
- Response times average only the regions that actually served the page, so a timeout never inflates the number.
- Where Postmark publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
