We too have been masively impacted by this event. I am getting zero information out of Epicor. I have created multiple service tickets only to be told that they are working on the issue and they dont have any updates. I have checked status.epicor.com throughout this event and that is completely worthless as the events have all been closed when they are clearly not.
I have reached out to our account manager, tried different avenues of approach with the various Cloud Services groups, no one will say anything. This is bigger than we think. Epicor really messed this upgrade up bad and is doing everything they can to not say anything.
This is reflecting exceptionally poorly on them as an organization and SaaS provider.
