Update
Our engineering team is continuing to investigate the issue that is redirecting GoToWebinar attendees to a 'Service Unavailable' page when attempting to register for a webinar, or to join a session from the software or a registration link. The problem appears to be intermittent and not affecting every attendee, and is not affecting the ability or organizers to start GoToWebinar sessions.
