HELLO,
What is going on with the SERVER???
Has anyone asked the slush pool owner?
Don't forget the Slush pool is on a different time than those of us in the US so at 0400 Slush pool time I would assume the owner is asleep. But maybe not and we post on here so fast when see something funny happening and over time, usually not very long really, it corrects itself somehow. By the time we flood the thread with posts it usually starts getting fixed. So they don't need to jump to repair for every short series of concerned posts we make.
Since I don't know how to set a backup mining site I'm stuck with what ever happens which is ok with me since everything does seem to get worked out on its own.
This is nothing against the question posted above by the member but thought it a good idea to remind everyone who forgot about the time difference. We n00bs have to stop being n00bs someday but for me seems it's going to be a long time from now. So much happens I've never seen before. LOL.

Setting up a 'backup pool' is simple. On the common mining software such as cgminer and bfgminer type [P]ool, then [A]dd, and enter the details of the pool. These settings can be saved ([S ]ettings, [W]rite config file. Saving the configuration remembers these settings so that they don't have to be manually reentered every time. Different pool switching strategies can be selected as well. The mining software monitors which of the pools on the list is 'alive'.
