Our system suffered a temporary login outage between 10-04-2019 21:45 UTC
and 10-04-2019 22:05 UTC. Certain people were unable to login during that time if they did not already have a session active.
We apologize for the issue and are working to ensure it does not happen again.
Thank you for your understanding!
