At 16:59 (UTC) today, suddenly most of the requests to seats.io resulted in 503 Service Unavailable responses, resulting in failed chart renderings and booking requests. At around 17:15 UTC the situation was back to normal.
We are still investigating the root cause of this issue, but for now all metrics are ok and the services are up and running again. We keep monitoring of course.
We're sorry. We'll get to the bottom of this and prevent this from happening in the future.
