RESOLVED: Delays to processing times of CNF confirmation files – Friday 22 October 2021

During the early hours of Friday 22nd November we received an unprecedented number of confirmation requests into our UK Link System which threatened to cause a significant impact to processing.

Our team worked swiftly to isolate the huge volume of Confirmation requests received, suspending the 11am confirmation job in order to evaluate options and allow other processes to continue un-impacted. As part of the incident management process we also worked with market participants to ensure that any issues causing the generation of very high volumes of confirmation requests were addressed at source.

We advised yesterday that confirmations would be processed in a managed way throughout the course of the day and as a result you may notice confirmation responses being returned to you less quickly than you are used to. 

We are pleased to report that the processing of all confirmations was completed by the evening of Friday 22nd, and all resultant confirmation responses were submitted by this morning (Saturday 23rd October). Confirmation processing jobs have now been returned to normal schedule.

If you have any additional questions or concerns, please contact the Issue Management Team.
