April 20, 2018 – On Wednesday, April 18, an errant fire extinguisher system in a third-party data center caused connectivity issues that led us to halt the opening of all Nasdaq Nordic and Baltic Equity and Fixed Income markets as well as Nasdaq Commodities. Since yesterday, all markets are back in operation from our back up facility at Nasdaq PORT and will continue to operate from that facility.

Nasdaq CSD has accomplished failover of the core CSD system to our backup data center and is providing all the core CSD services to its clients. Work to restore some surrounding systems of the Nasdaq CSD is still ongoing.

Nasdaq Nordic and Baltic took the time necessary to work with clients to facilitate a smooth transition from our primary to our back up data center and will continue to work diligently with data center provider to resolve the issue.

The reliability of our market systems is essential to our ability to provide a fair and efficient trading and settlement environment for our clients and other market participants. We have committed our full resources to the prompt resolution of this matter, and will take necessary actions in order to mitigate future risks.

We sincerely regret any difficulties this has caused you and your clients. Should you have any questions or need any assistance on the above, please do not hesitate to contact the Nasdaq CSD by addressing the e-mail to csd.ops@nasdaq.com.
