Following the previously announced planning for the validation of the cable length adjustment approach on selected Deutsche Börse Order Entry A-side connections, Deutsche Börse would like to inform participants of an update to the planned activities.
The activities on Saturday, 21st November 2026 will now be limited to preparation activities. The validation of the cable length adjustment will take place on Saturday, 28th November 2026.
Participants with affected connections will be requested to verify connectivity to the Connection Gateways and confirm receipt of technical heartbeat messages following each maintenance activity.
The updated schedule is as follows:
Activity | Scope | Planned Date | Support Window |
Preparation | RFRA3411 and RFRA3412 | Saturday, 21st November 2026 | Sunday, 22nd November 2026 – 08:00 CET – 12:00 CET |
Validation | RFRA3411 and RFRA3412 | Saturday, 28th November 2026 | Sunday, 29th November 2026 – 08:00 CET – 12:00 CET |
This timetable is also available in the T7 Weekend Maintenance/Activity Overview.
The purpose of the validation remains unchanged and is to confirm the planned adjustment approach under controlled conditions ahead of the broader cable length normalization of Deutsche Börse participant connections currently planned for Q3 2027.
Affected connections will be temporarily interrupted during the respective maintenance activity.
In case of issues, participants may contact their Technical Key Account Manager via their VIP number or cts@deutsche-boerse.com during the support window.
