simply awful "luck" last couple of days...what have there been 2 or 3 blocks total ? blocks are lasting between 5-12 hours a pop.
Just for info in case anyone is interested BTC Guild has been experiencing slow mining troubles also and has paid one block twice yesterday and now taking it back. They are also stating they have NO IDEA why the sudden slow down in the btc domenon.

Here is a recent posting by them:
A block was paid out twice earlier today due to a severe slowdown in the bitcoin daemon used to scan for new blocks. This block has been removed from the payment history and the shifts since it was already paid once. Rewards will have decreased by 1 block for all users that were active between shifts 14027 and 14036. This should not materially affect overall rewards for any users. If a user's balance has gone negative as a result, it is highly unlikely their balance will remain negative by the time those shifts are closed due to additional block solves.
The exact reason the bitcoin daemon became so slow is not known, but secondary checks have been put into place to prevent a double payment from happening in the future.

So I'd say this is a btc wide issue - just my opinion since I'm a n00b.
