those don't look convenient at all comparing to wisdom (when it was working properly I mean). at the end of the day there's a lot of charts at blockchain info however they haven't come up with an idea to combine hashrate and difficulty so that people could see where things going.

I guess wisdom's problem is related to segwit implementation cos there was a week or so in september when the chart stopped updating at all. imo it got back up by some happy coincidence, don't think it's because somebody recalled that they need to maintain this service.
