Outage for Some On Demand Customers

update: things are back online.  It turns out that our colo had a bad patch cable in place that came lose and caused this outage.  These things happen, so I'm going to look for reasonable ways to make that path redundant.

We have just detected an outage with our LA datacenter that is hosting half of our On Demand customers. 

I am working with our colo support staff to troubleshoot, and will post updates.
