A temporary outage for Roku Channel Store, activating devices, and billing is happening in August.
“We are migrating to new and more scalable servers to accommodate more Roku customers and partners. This migration will take place on August 23, 2017 from 5:00am to 11:00am PT.
While consumers can stream their favorite channels during this time, other services such as activating new Roku devices, accessing the Roku Channel Store, and making select streaming purchases through Roku Billing will not be available during the maintenance window.
We appreciate your patience and support as we make these improvements to scale the Roku platform.”
So essentially, if you aren’t purchasing a new service or activating a Roku you have nothing to be concerned with. If you are activating a Roku or purchasing a service, you will have to wait until after lunch on Aug 23rd to do so.
