We have deployed a new patch to help with debugging, and from the initial looks the load may have to do with some queries to our database clusters. We will keep you updated as things progress.
At the same time we are continuing to look at setting up multiple Channels for each region, but it will take longer than expected as we need to work with solving some potential dupe issues first that could arise when we implement Channels.
We are continuing to investigate and improve things as quickly as we can.
Thank you for your support!
