Unscheduled downtime incidents in Q1 2017
| Date | Start time [CET] | End time [CET] | Duration | Description |
|---|---|---|---|---|
| January 2, 2017 | 7:05 PM | 7:16 PM | 11 | 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. |
| March 8, 2017 | 3:38 PM | 3:59 PM | 21 | Due to extreme load on our system and configuration which was not optimized to handle this load without impact the entire environment, we had outage of the service. |

How is Uptime Calculated?
The uptime calculation is based on the following calculation (as defined in the Alma 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.)
