Guys, yes its down. Bytemaster is probably away / asleep. This is still beta and no doubt its been DDOS by another mining pool out of spite. Once bytemaster is awake he will investigate.
THIS HAPPENS ON ALL POOLS not just this pool. Its a regular occurrence in the PTS world at the moment as its very new.
Once things settle and networks get stronger, this will not happen as much as it does with all pools.
