** Update @ 5:09 AM PDT **
Connectivity has been restored. https://my.gogrid.com is back online.
The load balancers in front of my.gogrid.com were in an unstable state. To resolve the issue, we disabled one and failed over, resulting in service being restored. We apologize for the service interruption.
We're aware of a problem with my.gogrid.com and are presently working to resolve the issues. The GoGrid API has not reported having the same issue and should be available.
