There is an open AWS issue that is causing a disruption with calendar push notifications. Any customers who utilize a calendar integration for interview scheduling are impacted. This means there is a delay between what is listed as the calendar availability in Outlook/Gmail and what we see as their availability in Yello. The issue above is the only client impact we are aware of at this point, but given this is an ongoing incident for AWS we are monitoring closely. We will provide an update if we see any other client impact. No action is required of clients at this time. We have to wait for the AWS issue to be resolved. We will provide an update once we confirm the AWS issue is resolved.
