SteemData has been stuck on block 10,629,436 for a couple of days . This is because I had not upgraded the node or any of the code running SD in time.
For the past month I have been working on a new Python library (TBA), which moves away from websockets, and uses more transactional http to communicate with steemd. I have spent a lot of time improving, refactoring and fixing various issues within it, and it was not ready for HF18 or SD a few days ago.
I didn't think this would be a problem, however to my surprise, I have been contacted by more people than expected - people who rely on SteemData for their applications.
The good news is that SD is now running on new, experimental Python library, and is going to catch up to the head block today. Syncing will be faster once I deploy my own steemd node.
Also, there is now a very basic support for comments.
