My name is Nick, Head of Engineering here at EKM.
I wanted to let you know that your EKM shop will be unavailable for approximately 10 minutes starting at 11pm tonight (Wednesday 18th January 2017). It won't be available because we're upgrading our network infrastructure to ensure your shop performs at the highest level.
Our engineers will be on site and will continue to monitor the network after the upgrade is complete.
Thanks for understanding.
