... Failover when a sub-pool crashes takes about 4-6 seconds to kick in, meaning you can point your miners at one IP and it will automatically put them at an internal pool. ...
So it sounds like you are collapsing the multiple names (uswest, useast, uscentral) down to a single address with multiple servers behind it. If this is the case, please post the DNS name of this "one IP" as soon as possible so that we can get our miners reconfigured. (And point that DNS somewhere useful in the meantime... )
Thanks for the hard work.
