We are actively investigating the root cause and mitigation of degraded performance of both the async analytics endpoint POST stats/jobs/accounts/:account_id and synchronous analytics endpoint GET stats/accounts/:account_id.
The latency and amount of 503 errors significantly increased at 2017-08-22 05:00 UTC. Urgent action is being taken to decrease the latency but no ETA is available for complete resolution.
The asynchronous endpoint has had spikes of degradation since 2017-08-15 02:00:00 UTC. Due to the nature of in-order processing, a backlog may be created for queued jobs. In case of any issues with async jobs stuck in PROCESSING state, the recommended path is to use the DELETE stats/jobs/accounts/:account_id/:job_id endpoint and retry once the issue is resolved.
This thread will be updated with the latest status until the issue is completely resolved.
