This incident has been resolved. The new Rewards Engine is running smoothly and we have restored the Miner app.
During this outage, we have replayed the Rewards Engine from the Binance Data Fetcher (except for the 1-hour missing gap that initiated this issue), and have allocated liquidity rewards to bots running during that time.

We are putting up the maintenance page in order to deploy a fix to the back end system which should resolve the current issue with Hummingbot Miners.

At approx 2:00am PST last night, our Binance data fetcher went down; after one hour, it self-resolved and is now back online. During this 1 hour gap, we were not able to collect trades or orders. This gap locked up our Rewards Engine, which is responsible to processing the data and allocating rewards. Since the Rewards Engine component is down, Hummingbot Miner is not displaying any data.
Our Binance data fetcher is currently running, so any bots running during this time should get credit for its orders. We will replay the data and allocate rewards when the Rewards Rngine is back online.
We are investigating why this issue occurred. We were planning to deploy a partial fix to the Rewards Engine today and will need to see that that fix addresses this issue or if more work is needed.
