eleuthria, you are doing a fantastic job. We know this is not your primary job and are working on the pool every chance you get.
We, the mining public, can be patient while you work on setting up your fifth server in less than a month.

To all BTC Guild miners:
You will experience some problems when the new server is put online. There is no way to avoid it. All the servers must be in sync and there is no way to do that without some service interruptions.

While BTC Guild is growing, consider setting up a "back-up" pool.

You can configure your miner to mine at a backup pool especially if you use poclbm.exe.
Run two instances of poclbm per GPU. Use the "f" command to give one pool priority over another. The lower the "f" value, the higher the priority.
-f30 to one pool will have priority over -f60 on a second pool.
This will split your GPU processing power to about 92% | 8% between the two pools. If one pool is idle, poclbm will automatically shift your mining power to the backup. This is even easier to setup and monitor using guiminer.
This has worked flawlessly for me and has always kept my GPUs at 100% through BTC Guild's growing pains.
