Fantastic.
Will you please verify that all data is showing on SCADA for the MBR process? Jesse had mentioned earlier that the analogs were reporting but not the digitals.
Also, please forward a service report.
Thank you David!

System is restored. Both servers are operational, and engines are running on both servers. I've been monitoring and checking for the last ~20 minutes. Performance looks nominal, including Historian/trending.

I've stopped the platform and all engines on app-server-1. One of the engines was stuck in a sync cycle with its redundant partner on server 2. I stopped the partner engine on server 2 temporarily to allow a clean termination on server 1.
Everything is running on server 2 now. I'm monitoring for a few minutes. Then I will perform a repair install on server 1.

Kevin,
Thanks for sending. This is some good background info. I agree a repair install is likely needed. Let me try to login. I assume VPN remote connection is still working.
