As of 1:15 p.m. CT on March 6, 2019 we are aware of an outage on the RT Site not allowing you to view content and prompting you to sign up for FIRST membership.

We're working on a fix and appreciate your patience.

Edit - Update at 2:50 p.m. CT - Looks like everything is working as expected again. We're continuing to observe and watch, but it all seems stable again.
