We've identified a processing backlog caused by a network slowdown between our build servers and storage provider. It's affecting butler pushes, including small patches. Builds are still processing, but as of this post there's a delay of several hours.
If there's an emergency and you need to get a new file up on your page, you can upload from the browser to skip butler processing entirely.
Edit: The network issue seems to be resolved, so the backlog is catching up now, some larger builds might take some time but smaller games queue is mostly processed.
