Update 1/19 12:55p CST: This issue should be resolved, and normal performance should be restored. If you are still noticing problems with pages loading very slowly (10 seconds or more), please post the page that is loading slowly in the comments, and we will investigate.
We're noticing some performance slowdowns on the Webervations 2.0 admin site. Webervations 1.0 is not affected. We are working to resolve this problem as quickly as possible, and will keep you updated.
