We apologize for the uncertainty our downtime has caused. The scheduled downtime was to replace our old trading engine with a brand new trading engine – an improvement that customers have long asked for and that we have long been working hard on. We still have some more work to do before the new trading engine is as good as we want it to be, but this week’s replacement was an important first step to having a better trading experience. Our system is replicated in development, where all tests passed. However when the new engine was moved to the production environment, regression tests picked up a condition that proved quite difficult to track down. Further insight into the downtime and a description of actions we plan to take in order to improve the client experience will be provided via a retrospective Kraken blog post, to be published in the coming days.
With trading now resumed, the engine’s performance will be closely monitored. The site will come down if needed, which may occur with little to no notice. Please continue to refer to status.kraken.com for real-time updates and important announcements over the next few days.
Lastly, in appreciation for your loyalty to Kraken, we are activating zero fee trading for all clients (across non-margin trades) starting today and lasting through the end of this month.
Thank you!
The Kraken Team
