Mining isn't so effective in the past 24h?

Maybe it's just me, but mining hasn't been so effective in the past 24h. On BTCGuild, I usually get rewarded every 3-4 hours, but yesterday I had to wait 13, and haven't gotten that much. Same thing with Ghash, I've been mining @ 441Gh/s for 2-3 hours today and my balance has not changed (pending is at 0 as well). What is going on?

Btcguild hasn't been very lucky. Only managed to mine one or two blocks per hour. I assume other pools has been luckier.

It is your pool luck.  With BTC Guild it has good and bad days.  I personally moved it to backup pool as I felt to many bad day's.  I love their site though.

Slush's pool luck has also been down A LOT in the last couple of days.
Even looking at P2Pool, does not look like they've had "out of the ordinary" luck in the last 48-72 hours, albeit a couple of quickfire blocks a day or so ago.
So looks like it is grim all round ....!
