This.

My balance showing as of now is what it was ~24hrs ago.  When the web site went down, my workers kept going for about 12hrs until the pool went down (~12hrs ago).  They switched over then to a back up for a couple of hours then the multipool mining pool came back up and they auto switched back.  I noticed it and manually switched to a backup because of the note on the website down page saying to switch miners.  None the less, I was mining on Multipool for a good ~12 hrs yesterday but no sign of the coins.  That is a lot of time and coins.  As others have said, where did all that hashing power go and where are the coins I mined?

If there was a problem that bad that resulted in lost coins, the pools should have been taken down (and left down) right a way.  For now I will reserve judgment, maybe everything we mined yesterday will show up in our accounts eventually.  For now though it is not obvious that they are up and working yet, so I am still mining elsewhere for now.
