Yeah, many of their alias URLs are not working lately.
The other night (Monday?) I was able to get the betmill.com home page to come up, but it wouldn't log mw in.
So I clicked on the 'chat help' (which worked), and the CS guy asked me to try the ms2.wagermillenium.com address (whihc worked at the time, but doesn't since).
I also asked if they were being attacked (denial of service) and the response was 'no'.
