I just went back and read the conversation again. At the time, I mentioned that I was previously aware of votes and posts showing up late, so I guess January 21 would be "at the latest", but it almost certainly started some days or weeks earlier. TBH, It seems to me like we've been having problems ever since the end of August, when the apparent dos attack happened. For example, this SteemDB link ground to a crawl after that outage, and it is still only caught up to September 10. (I used to use it in one of my PowerBI graphs.) From my vantage point, there's no way to tell whether these problems are all interrelated or not.
