Guys,
Small update and summary on changes in pool infrastructure:
I added several failover servers in US, EU and Asia to keep the best possible performance for users (no disconnections, no issues with authorizations, lowest ping possible). I had to restart stratum servers but it was last time

Because I had a lot of request I added two static ports and here is a summary:
Available addresses:
zec.coinmine.pl - geolocation, load balance, failover - use it to get the best possible ping for your location
zec-eu.coinmine.pl - load balance, failover - if for some reason you want to mine directly on EU servers
zec-us.coinmine.pl - load balance, failover - if for some reason you want to mine directly on US servers
zec-as.coinmine.pl - load balance, failover - if for some reason you want to mine directly on Asia servers
Available ports:
7007 - default vardiff port
7077 - default vardiff port for big hashpower
8008 - static port - diff 20
8088 - static port - diff 500
Any questions? please ask
