Update

We are continuing to investigate this issue. The problem is limited to customers using Atlas Timestamping with the Japanese Qualified Timestamp service provided by our partner in Japan. However, we are yet to identify the root cause for the high failure rate of these timestamps.

Investigating

We are currently investigating a slightly increased error rate on the Atlas TSA service, resulting in customers receiving HTTP 503 errors in a small number of cases. Retrying failed requests should result in a successful response. We will provide updates as we identify the cause.
