This platform issue caused request timeouts for many of our API clients, between approximately 00:30 UTC and 13:00 UTC on January 1st.
This resulted from an unprecedented number of API requests on New Year's Day, occurring in a way that did not allow our platform to efficiently auto-scale, due to an unexpected bottleneck between our database and cache.
We began investigation as soon as we became aware of this issue, and resolved it with a deployment later in the day.
Although a small number of clients continued to experience occasional timeouts for up to 48 hours afterwards, we have not experienced a recurrence of this issue. We have since made further infrastructure updates to safeguard your service.
We sincerely apologise for any inconvenience this may have caused you. Please rest assured that we continue to closely monitor our API platform and responses for unexpected behaviour, providing you with the consistent and stable service availability you expect.
Please don't hesitate to contact us if you have any questions or concerns about this incident.
