I can honestly say, after using slush for a couple of days while btcguild was down, that I feel sorry for the people who mine with slush full time.
Can you explain why?
Should be obvious - if you don't switch pools when one is DDoS'd then your rig is sitting idle not making money.
Slush - what's the word on service? Are you considering any kind of SiteBacker DNS load balancing to help with traffic distribution between colos - that's helped some of my environments with DDoS.
I'm sorry, but I think smackdady is all right.
After atack in sunday, I have about 0.011 BTC for any block with my 440 MHash - about 0.3 for day.
On Monday, I have only 0.008 for block. Now with ~210 MHash I have 0.003 - 0.005 for block.
I wait result today but supose, I will have only 0.11 BTC for 24h.
On btcguld, with 230 MHash I have about 0.0050 for each block (0.163 BTC in last 24 hours). This about 40% more.
Something its not good with this pool.
