Modifying your Data Center in Hyperspace
On occasion, NetSuite will modify your Data Center.
If you need to modify the Data Center settings that Hyperspace uses you can easily do that inside of Hyperspace. Login to Hyperspace and go to Account Settings > NetSuite settings.
You will see a button that looks like this at the top of the page.
Click this button and let it run for 3-5 minutes.
You will see a setting further down the page that looks like this.
This is where you select your Data Center. There is no save button, you just select the option from the drop-down menu and Hyperspace will use that data center when syncing to NetSuite.
