Resolved after 2 hours 38 minutes, affecting US - Academy Platform, on August 25, 2025.
Between 13:15 and 17:08 UTC on 2025-08-25, users of the TI platform experienced slower than normal response times due to an internal scaling issue. The component which controlled internal DNS resolution failed to scale under load, resulting in higher-than-expected response times at peak traffic. The infrastructure team identified the root cause and manually scaled the DNS resolvers, restoring response times to expected levels. An update will shortly be applied to enable auto-scaling for this internal component, ensuring that this issue does not re-occur. We apologize for the inconvenience and are committed to ensuring improved reliability going forward.
