| We experienced a simultaneous network device failure on our backbone infrastructure. As a result of this failure, a failover to the adjacent redundant network device took place. Due to a network component configuration setup the failover took longer than expected and caused the system disruption. |
February 28, 2017 | 10:18 AM | 10:56 AM | 12 | We experienced a network device failure on our backbone infrastructure. The outage was due to hardware problem that caused interruptions to production traffic flow in our datacenter network – due to the short intermediate interruptions (2-3 minutes), full failover process to redundant devices was not initiated. To resolve the issue Ex Libris engineers worked with the vendor support to replace the device. |

How is Uptime Calculated?
The uptime calculation is based on the following calculation (as defined in the campusM 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 11 months period
Z = The duration (in minutes) of any SLA Exclusions* during these 11 months
*SLA exclusions are defined in the contract SLA (e.g. Scheduled maintenance, etc.)
