TMX Disaster Recovery Dates for 2021

TMX is pleased to announce the following dates for 2021 Disaster Recovery testing:

Internal Disaster Recovery (DR) test on Saturday April 24, 2021.
External* Disaster Recovery (DR) Pre-Connectivity test on Saturday September 11, 2021.
External* Disaster Recovery (DR) test on Saturday October 23, 2021.

The purpose of Internal tests is to validate the failover of TMX's primary trading and feed delivery systems to backup systems. During the Internal DR test, clients will experience a network outage on connections to the TMX Markham data centre. Any alerts generated should be suppressed or ignored. All post-test validation will be completed by TMX and no validation activity is required by TMX Clients. TMX will issue a notice when regular operations have resumed.

* During the External DR tests, client participation is strongly recommended. A subsequent notice detailing all activities pertaining to the test will be disseminated closer to the testing date.
