API Post-mortem: High latency
(Sunday 11th March 2018 23:36:49 UTC)

Over the past few days, we have been experiencing several short periods of high latency during excessive bursts of traffic. We would like to apologize for any negative effect this has had on the immediate delivery of notifications to your users.

After attempting several remediation strategies, we have been able to find a solution that appears to be working quite well, by utilizing a Redis caching mechanism to drastically reduce load on the database cluster. We will be closely monitoring latency over the next few days to confirm that the issue is indeed resolved.
