There is currently a mismatch within the Central Switching Service (CSS) system functionality and the legal text within the REC Switching Data Management Schedule. Within the schedule the retry strategy is defined as “retry sending the Market Message at intervals of 10 seconds, 20 seconds and 30 seconds from each attempt to send the Market Message. If these retry Market Messages also fail, then the Market Message shall be retried at intervals of one hour up to a maximum of 12 hours; after which delivery of the Market Message shall be abandoned and a Switching Incident raised in accordance with the Switching Service Management Schedule”. However, in response to an incident in 2022, the CSS Provider updated the retry strategy. This change seeks to amend the legal text in Section 2.4 of the Switching Data Management Schedule to reflect the retry strategy which is currently in operation in the CSS system.
