Thanks for the report. We had a bit of extra web site downtime as we were working on lots of backend sysadmin type of things. Our apologies for that.
Just for future reference, even if the website "goes down," the mining will still be active and shares will still be counted accurately. That's one of the many advantages our architecture has over many other pools. They're disjoint parts, so if one goes down, it doesn't affect any of the others.
