We made some domain changes and we are trying to validate that other people can see this.
We have nailed the issue down to DNS propagation. If you look up you can now see that the address is now just norcalfjs.com and not norcalfjs.ning.com
This should resolve by this evening, if your having intermittent issues you can try changing your DNS settings to thegoogle DNS servers (which is a good idea anyhow, much faster then most ISP DNS servers).
we apologize for an inconvenience.
UPDATE:
Due to some issues we have reverted back to the old settings. We will try flipping the switch a future date.
