Running into issues as well. Difference is that I can get to the log-in page, however it says that the password is wrong and/or account no longer exists.
I once had a paid account with them, as I am all about supporting the smaller independents. However, due to some failures to deliver on their end, I let it expire. I have only known of an outage once in the past few years, and it was back up within a few hours. This time, if it does not come back, I am not too concerned...
