Steemit took to Twitter today to announce to their fellow-Steemians that Steemit is back up and running and fully functional after having suffered from a bug in the curations reward curve.
According to a blog post from Sept. 3, Steemit is now fully operational again, as are all Steem applications leveraging their API. The chain halted over the weekend due to a bug in the curations reward curve, which was apparently unrelated to the previous halt or the so-called delegation bug.
