UPDATE ~ I was just able to login to my account - seems like they're getting the high traffic under control.

This is the current message Bittrex has posted up when attempting to login - it's a little bit more informative then this mornings username/password errors. Hopefully they're back up sooner then later.

We are aware of login issues, investigating.

We have temporarily disabled account logins while we investigate. If you previously recieved invalid username or password when attempting to logon do not panic and do not attempt to reset your password at this time.
