Update
As of 15:08 UTC, we are broadening the stated affect to Learnosity from the ongoing partial AWS outage, to include delays to scoring. This continues to affect a very small number of customers.

We are starting to see a small number of scoring delays and our asynchronous scoring queue is performing as designed and queueing affected sessions for rescoring. We will continue to monitor all performance and update when we know more. We are still trying to work with AWS to learn more, as well.

Learnosity Support and Systems Engineering teams are continuing to actively investigate the issue, and will follow on with an update and resolution as soon as possible.

Update
As of 14:44 UTC, we are still investigating the impact of a partial AWS outage.

We are starting to see some errors where AWS EC2 instances are slowing connections to the Learnosity databases. Attempts to span new EC2 instances are failing, consistent with AWS description of the problem.

This appears to still only affect a single AWS Availabilty Zone, so not all customers are being affected. However, we are continuing updates in case this issue grows.

Learnosity Support and Systems Engineering teams are continuing to actively investigate the issue, and will follow on with an update and resolution as soon as possible.

Update
As of 14:33 UTC, we are continuing to investigate the impact of a partial AWS outage.

As a precautionary measure, we're alerting degraded performance in availability of assessments but, according to AWS, this is allegedly only affecting a small subset of EC2 instances launched after October 08, 2020, at 9:37 PM PDT within a single Availability Zone (use1-az2) in the US-EAST-1 Region. So this may not be affecting all customers.

Learnosity Support and Systems Engineering teams are continuing to actively investigate the issue, and will follow on with an update and resolution as soon as possible.
