I'm having the same issues. The WIS post asked people to submit a ticket if they are having issues so I did. Here is their response. Fingers crossed the mirror site gets up sooner than later.
Our initial plan to work around workplace filtering of our site hasn't panned out. The good news is that we're working on getting the www.wisjournal.com mirror site back up. We don't have a definite timetable yet, but we're hoping it won't be too long. We'll let you know when that's available again.
We apologize for the inconvenience, and appreciate your patience in the meantime.
