I am also unable to access ebenefits. I am receiving an internal server error page when I attempt to log in. I attempted to call DMDC support as I was unable to find any information regarding ebenefits being down and I couldn't find a support number for them. DMDC support told me that it is in fact an ebenefits issue and that I would have to contact them, and gave me their number. I attempted to call them and they are not 24/7 like DMDC support is, they only operate mon-fri 7am-7pm central time so I was unable to reach anyone.
