During an urgent and unexpected maintenance activity to replace a redundant network switch, a malfunction was triggered and caused both switches to fail. Cisco has confirmed that this malfunction is the result of a bug. The malfunction caused a network outage in the switch, which serves all server connections to the network, including to the central storage server in the Ex Libris Singapore data center.

Due to a human error related to the change management process, the June release was installed on the environment a few hours earlier than usual and caused an outage at an unexpected time. It was found that the verification process that normally stops an installation from being performed in an unapproved window of time contained an error and therefore did not prevent the installation. |

How is Uptime Calculated?
The uptime calculation is based on the following calculation (as defined in the Service Level Agreement):
"Uptime" means the total period in minutes during which the Service is available for access and use during this period.
“Uptime Percentage” means Uptime expressed as a percentage, calculated in accordance with the following formula:
Uptime Percentage = X /(Y–Z) × 100
Where:
X = Uptime
Y = Last 12 months period
Z = The duration (in minutes) of any SLA Exclusions* during these 12 months
*SLA exclusions are defined in the contract SLA (e.g. Scheduled maintenance, etc.)
