Looks like chain is stuck at block 1953796 for over 5 hours...
autoswitching multipools do that every couple of days, whenever the relative value of the token puts it into their cross hairs.
we're working on finishing up a daemon that auto-rents hardware and plugs into our tradebot tool to give the tokens an offramp. once its up and running we should see significantly fewer of the large difficulty changes that cause many hour long delays in finding blocks.
