Today we released an update to the site with some speed improvements and a couple of fixes.
You may notice some broken images and avatars across the site for a few days. We still have these images but they need converting to a new format.
A script will be run soon to sort out all of these images and return them to normal so there is nothing you need to do. If your avatar or post images are broken and you wish to replace them yourself please feel free to do so.
