The following incident summary was provided by Desire2Learn
Incident: Due to a network disruption in our hosting facility, clients were unable to access their Desire2Learn environment.
Start Time: April 19, 2012, 11:35am ET
End Time: April 19, 2012, 3:19pm ET for most clients.
A small number of clients had services that didn’t restart immediately and may have had impacts until 3:56pm ET.
Cause: There was a failure with a core network switch, and the failover to the redundant network switch did not occur properly.
Root Cause Information:
Desire2Learn would like to share with you some initial root cause findings. Some hosted clients have experienced SQL database interruptions since April 9, 2012. Hosting facility engineers have determined that these database issues were related to the core network switch beginning to fail and interrupting communications between databases.
We are working with the hardware vendor to determine the root cause of the core network switch failure. Technical teams are continuing to closely monitor the hosting facility network and hardware.
Desire2Learn is compiling additional Root Cause information and will provide you with another update on Monday, April 23, 2011.
We sincerely apologize for the impact the disruption this may have caused your organization.
