On Mar. 3, UK LSE informed of alternative site recovery (ASR) test.
UK LSE informed of an exchange alternative site recovery test that will be carried out.
Purpose
The ASR Test for UK LSE, TRADEcho, Turquoise and Turquoise Europe will include Group Ticker Plant (GTP) market data protocol; simulation of live service's disruption.
Serious enough to warrant a controlled system shutdown at the Primary Data Centre (PDC), followed by a recovery at the Alternate Site or Secondary Data Centre (SDC).
The simulation exercise will test the technical process of recovery and sequence of events during this process; the process of suspension and restoration of the market.
The communications between UK LSE and customers during recovery; customers' ability to connect to the Alternate Site and trade via their connection to UK LSE SDC.
London hosted customers are invited to participate in the ASR test; this will simulate a local platform issue and allow customer traffic routing between the PDC and the SDC.
UK LSE will undertake some intraday reference data actions which will include the suspension and/or restoration of instruments; recommendations for participation.
Effectiveness
The ASR test is scheduled for Mar. 29, 2025.
UK LSE, TRADEcho, Turquoise and Group Ticker Plant (GTP) customers need to register their interest to attend by email before Mar. 21, 2025.
Only those customers who register will receive further information and the schedule of the ASR test closer to the date of the test weekend.
