Firstly, we'd like to apologize for problems with channel manager reservation processing during night from December 6th. We'll learn from it and improve the system, infrastructure monitoring and our internal processes in order to prevent occurrences of similar issues in the future.
During planned update of the system, a performance regression was introduced into a component that is responsible for identification of travel agency emails within channel manager module. Reservation processing was therefore slowed down significantly for smaller properties and failing in bigger properties.
As soon as engineers were notified about the issue, they started investigating it, found the root cause, fixed it and updated the system.
