I have noticed a few WU's they have had problems with (client crashed when they was assigned these WU's). They have now removed them and it seems like everything works quite well, except that they have had some problems after the powerdown last friday (stats not showing up, servers not give WU's etc). Hopefully will they solve their problems and be back up and running to 100% soon again.

3/17/2003 PLANNED SHUTDOWN, FRIDAY MARCH 21
The power in our building is being rerouted and we are being forced to have a planned shutdown. We will likely take all of the F@H servers off line Friday, March 21 around 5pm PST and then bring them up around 1pm Saturday, March 22. The exact times may change slightly. We had a previous planned shutdown like this which went relatively smoothly and we hope that this will go smoothly as well.
