Integration Platform - HTTP 400 Errors

Incident Report for Spotler

Postmortem

On 24th June, between approximately 13:30 and 17:00 CEST webhook delivery for some integrated customers was disrupted. The cause was available disk space on a platform component falling below a safe operating threshold. An existing monitoring alert did not fire as expected, which delayed our detection and response.

Webhooks and API calls towards the integration platform returned 4xx/5xx error and their contents have not been stored or retried. Meaning data sent during this window may not have been received by the integration platform if webhooks are the only way of communication to the integration platform. Rest API was un-affected.

We have resolved the underlying disk space issue and have corrected the alerting configuration to ensure this class of problem is detected promptly in future.
