I'm still having trouble with the US server sometimes losing its connection, or taking up to a couple of minutes to accept shares, resulting in all stale shares, the EU pool is unusable because it's behaving in the same way but worse. I also assume that it's not my computers or internet connection causing it because my brother is having the same trouble. The server stays connected but stops working properly, meaning that I have to disconnect and then reconnect, something that I can only do if I'm at the computer and notice it.
I'm not nagging you here, I'm just wondering if you're aware of this issue, it affects your income as well as ours. (We're in the UK by the way, maybe this problem is less noticeable to you if the server is nearby).
Anyway, hopefully you'll be able to sort this out because other than that issue this is my favourite pool so far and I want to be able to stick with it, clearly you've put a lot of work into designing it.
Edit: I've also noticed that both my computers seem to do this together, and because I was chatting on Skype with my brother at the time I found out that his did at the same time too.
Are you using skype on your mining rig? Just curious. Also, have you done a tracert to the server you are connecting to? What does it show if anything? There are several things that can affect your connections so you need to go through them and see where the issue is.
When 875 miners are doing fine w/0 issues and you and brother have a problem then it is highly likely the issue is on your end somewhere. Do a little geekwork and we can probably help you fix whatever it is.
