I'm not sure of the exact time, but sometime around 4am last night the Steem Engine node crashed. The american devs were contacted, and restarted the node. The node had to replay and has now finished replaying. Steem-Engine is functional again. Sorry for the inconvenience.
For those saying this is the exact problem with a centralized service like this... we agree. The P2P layer that harpagon has been working on for a few months is nearing deployment, but has a bug in the code that's preventing us from launching it. The point though is that we're nearly done with the P2P system that should help prevent a single node from crashing the system.
Other things that are coming include- NFTs, accepting USD, and seems like a USD backed stable coin are all likely and I'm targeting Q1 for all of them. USD stuff is a small project (technically), NFT is a big project. When both of those are done we'll circle back and try to focus on site stability and increase load speed.
The cryptoconverter has run into a few hiccups. It's surprising challenging to get all blockchains interacting with eachother smoothly. I'm attempting to get another dev on the project there to help that work smoother.
As it turns out a lot of the work done for Splinterlands on integrating eth should be usable for Steem Engine. Hopefully soon we'll have ETH and all the ERC 20s tradable. Shortly after that I hope to have NFT bridges possible as well.
Good things are coming. Doing my best with a limited budget in a down market to make as much happen as possible. I apologize for any inconvenience. Thank you for your patience, and as of right this second all systems appear to be working.
