## Timeline of updates

- **investigating** 2025-12-10 03:40 UTC: We are looking into increased error rates and high latency across our APIs. This could be related to a third party outage.
- **monitoring** 2025-12-10 04:46 UTC: One of our third party providers is experiencing increased latency. This is causing a very small amount of the traffic hitting our APIs to error or have high latency. We are monitoring to ensure the latency and error rates don't increase while waiting for their team to resolve the issue.
- **resolved** 2025-12-10 06:09 UTC: This incident has been resolved.
