| October 13, 2023 | 04:34 AM | 06:31 AM | 114 | A misaligned internal process caused a massive usage on the internet traffic which ended up in a service disruption. Once the Exlibris engineers identified the issue the process capacity was limited and the service recovered. |
| October 25, 2023 | 04:42 PM | 05:57 PM | 75 | As part of our continuous efforts to maintain our environments updated and secured, we performed a non-disruptive update to one of our networking devices. Unfortunately, there was a misconfiguration which disrupted the service. Once the issue was found, Ex Libris engineers worked with the vendor of the device to revert the change and restore the service. |

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 by 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.)
