noticed that on 2019-05-14 there were ~8.5% less blocks produced than usual (about 4150 average usual and 3793 on 14th - all numbers i store in this spreadsheet). when i started digging i noticed that between blocks 938464 and 938626 all block times were 1 minute and all (almost) of them were produced by NiByGF4sjAux92mvQhEV1Y9EhUgLCKhGjx
why block production stalled between 938464 and 938626 ?
is NiByGF4sjAux92mvQhEV1Y9EhUgLCKhGjx a new genesis proposer ?
