After thorough investigation, we determined that we hit some unforeseen I/O limits with our database. The combination of a cache flush due to a restart, recalculation of some statistics, and peak load resulted in brownouts and occasional errors in our application.
To remediate this type of resource exhaustion, we've purchased additional I/O capacity from AWS. As always, we'll continue to monitor and tune our database configuration in response to the large amounts of data that we process.
There was no impact to customer data during this period. The application is accessible and operating as expected at this time.

To minimize further disruption, we moved our planned update outside of US business hours. Changes will release at 6pm Pacific Daylight time. We apologize for the performance issues today and thank you for your patience while we determine the best course of action to rectify the situation.

At 2pm Pacific Daylight time our team will release an update to address performance issues. There may be a degradation in service while changes roll out until the system stabilizes.

We've identified the source of the performance issues, and will make changes later this afternoon (Pacific time) to correct the problem. There may be intermittent performance issues in the meantime (slow page loads and scheduling). We're currently analyzing site traffic history to determine the optimum time to make updates. We'll post again prior to updating to make you aware of the time we expect to make changes. The app will be accessible during the maintenance period.
