We use the proxy setting for images here so all non-SSL images are stored on the server to avoid SSL errors. It's quite a chunk of images that have been posted over the years so we had to re-balance the volumes last week. It was more temp. and today we had to take the server offline for a second to do a more formal re-balance.
Should be resolved now. We used to have multiple instances of AWS hosting forums and consolidated to a single one last night. HomebrewTalk.com was the last site to move over and we completed it super early this morning but the load balancing server had some hiccups once everyone was on.
