1. Introduction
Deutsche Börse will further improve cable-length normalization for Colo 2.0 10 Gbit/s participant connections in the Equinix FR2 co-location facility. This initiative is attended to further reduce differences in the physical length of participant connections and to provide even more consistent technical conditions across the Colo 2.0 infrastructure.
As a first step, a limited validation will be performed on selected Deutsche Börse Order Entry connections in Q4 2026.
Based on the current planning, the cable-length adjustment for Deutsche Börse Order Entry and Market Data connections is scheduled for Q3 2027. The activities will be performed during announced maintenance windows.
Affected connections will be temporarily interrupted during the respective maintenance activity. Detailed dates, affected services, and participant testing windows will be communicated in advance via Implementation News.
2. Required action
No changes to participant trading applications or network configurations are required.
Participants whose connections are included in a maintenance activity will be asked to verify connectivity during the testing window specified in the respective Implementation News.
The planned checks may include verifying connectivity to the Connection Gateways and the receipt of technical heartbeat messages. Dedicated technical support will be available during the announced testing windows.
3. Details of the initiative
Deutsche Börse is currently performing infrastructure preparation and measurement activities across the Colo 2.0 environment. These activities are a prerequisite for the planned cable -length adjustment of participant connections, and the resulting measurements will be used to determine the required adjustments for individual connections.
Before the broader adjustment of Deutsche Börse participant connections, a limited single-weekend validation will be performed on selected Deutsche Börse Order Entry connections in Q4 2026. The validation will be used to confirm the cable-length adjustment approach under controlled conditions.
Following completion and review of the validation, the cable-length adjustment for Deutsche Börse Order Entry and Market Data connections is currently planned for Q3 2027. The activities will be carried out during announced maintenance windows.
