My miners seem to be running smoothly on this pool. None of them have fallen over to another pool in the last 2 days. (which I believe was due to unscheduled maintenance)
So this tells me the issues are on the front end (which I am seeing too). I am sure these issues will be ironed out. All new pools go through these learning curves, I'm sure.
whats the front end, the part that handles incoming hash
No the front end is the website that displays statistics etc. The stratum server (that deals with mining/incoming hash, and other parts of the back end (payments, updating statistics, managing block finding etc) is having no issues what so ever).
The problem seems rather intermittent with the front end, as it only effects some people and only sometimes. As they could try again in 5 minutes and it works perfectly fine for them.
