It seems likely that you are encountering issues with retrieving traces from the Phoenix server due to potential server-side limitations or configuration issues. According to the <https://docs.arize.com/phoenix/tracing/how-to-interact-with-traces/extract-data-from-spans|Phoenix documentation>, you can specify a time range when querying spans, but if the server is returning 503 errors, it might be due to server capacity or configuration issues.
You might want to check the server logs for any errors or warnings that could indicate why the service is unavailable during those specific time frames. Additionally, ensure that your server is not hitting any resource constraints, as mentioned in a <https://github.com/Arize-ai/phoenix/issues/6308|GitHub issue> where similar problems were discussed. Would you like more detail on how to troubleshoot or configure your server to handle these requests better?
