Reminder: TMX External Disaster Recovery Network Connectivity Test
|
Reminder: TMX External Disaster Recovery Network Connectivity Test Please be advised that TMX will be conducting an External Disaster Recovery Network Connectivity Test on Saturday, September 23, 2023. The purpose of the connectivity test is to provide clients the opportunity to establish and confirm network connectivity to the Toronto Computing Facility (TCF) DR data centre. TMX will simulate a "disaster" at the primary data centre (MCC) and failover TMX's primary trading and market data feed delivery systems to backup systems at the TCF DR site. Clients will experience a loss of network connectivity for circuits to 3500 Steeles Avenue, Markham data centre during the test. Any alerts generated should be suppressed or ignored. Network connectivity is anticipated to be restored at approximately 11:00 PM ET on Saturday, September 23th. A notice will be sent to the street when the test is over and normal operations have resumed. This activity is intended for clients to confirm DR site network connectivity. Clients are advised to verify using telnet to Unicast destinations (OE session; Feed Recovery Sessions). TMX does not support PING and therefore cannot be used for verification. Other Disaster Recovery (DR) tests are scheduled as follows:
*During the External DR tests, client participation is permitted and encouraged. Notifications will be communicated to test participants as the exercise moves through the scheduled phases. Please provide your email to TMX Market Operations if you are participating in the DR testing and want to be included on these notifications. **Please remember to not release your Production queues during the test** |
