From 12:10 PM - 12:37 PM PST, some customers may have experienced an elevated rate of errors and timeouts for presence calls in our US West and US East PoPs.
This occurred because we received an unusual traffic pattern that significantly elevated our 90th percentile latencies. This caused delays which lead to timeouts for some customers. We were able to mitigate this traffic and reduce the latency and thus eliminate the timeouts and errors.
Mitigation Steps and Recommended Future Preventative Measures
We have already implemented more proactive measures to prevent this in the future. Additionally, we are always working to ensure the utmost robustness of our service so that any traffic can be handled without incident.
