They expect to be down 4-6 days now:

Update for April 27th

Given that this happened in spite of having applied all current security patches from the companies that provide our forum software, we are in the process of employing additional security experts to ensure that we are in compliance with the highest security measures possible.

At this point in time we anticipate forum downtime to be within 4-6 days.

During the forum outage, both the 2+2 Magazine and the 2+2 PokerCast will be available. This includes the release of the next PokerCast episode and the May issue of the magazine. You can also read the 2+2 archives going all the way back to 1997.
