The only pool is not down but I am mining with a cloud service and since yesterday I had to restart the miner several times, because the pool does not mark anything. I can see the accepted shares in the miner but in the pool there is no active worker. This same happens sometimes with the pool of ocminer and never happens with the other pool of other currencies. When it begins to fail appear in the miner some red lines saying a stratum connection failure. My speed test assures that it is not problem of my side because I have 1ms ping, 387Mbps down and 385Mbps up.
