*sigh* People need to move to Stratum, The Stratum part of BTCGuild has been working just fine for a Long time
The Getwork side of the pool frequently gets attacked via DDoS because its a Peice (approx 9-14%) of the pools hashrate, People dont want to see a massive pool because it might reach 51%, But they dont want to "down" what is perhaps the best mining pool.
DDoS'ers just dont want it to be so close to 51%, So they attack the Getwork that Botnets/Old Workers use

Oh, On a compleatly unrealted note, Hooah!, Battlefield is leading the poll!
