I've received confirmation from Azure support that we were the target of some underlying load balancing operations that caused our intermittent failures. We've been looking good since 11:45am MST. With the responses from Azure, we feel comfortable at this point considering this issue resolved.

We've identified the source of these issues as our underlying storage layer. We're working with our cloud service provider (Azure) to determine the cause of these issues. We've adjusted our services as much as possible to limit the impact, but will continue to see a small percentage of issues and degraded performance until we are able to get this resolved with Azure support. Thank you for your patience.

Beginning at 7:20am MST, requests to get the next activity for students started experiencing intermittent failures. Students may experience issues where they are logged out of the student app and need to log back in. This is affecting approximately 5% of requests for next activity, but retry logic will limit how often this affects students. We will keep you updated as the investigation continues.
