We are seeing some issues with Managed WordPress hosting in our US data center which is causing slow setup times and outages for a few customers. We are working to get this fixed as soon as possible. Thank you for your understanding.

Our Managed WordPress control panel still refuses to load, but it looks like you all are already working on the issue. I talked to tech support yesterday morning and they said that it was a known issue, after trying to open it for me. Hoping things will be resolved soon!
