Ning there is a problem with loading and it's taking ages to load changes and is getting really frustrating. Not just adding any css but just simple changes in the design studio. Sometimes it's ok but most of the time not. For instance I started writing this after making a simple change and the site is stuck waiting for st4.ning to load and it's still waiting over 5 minutes now. Also it waits for storage and static.
Please can this be looked into ASAP.
