People have asked me how long the miner who solved the block has been mining for.  I don't know exactly since their hashrate may have fluctuated over that time. However, assuming they always mined to the same address, they currently have 2486021304645 shares. Dividing that by the current difficulty of 13732352106018.34 that means he found the block at about 18% diff, so in less than 1/5th of the expected time for the current diff.  If they've been mining with a stable 70TH all along, they've been mining for a very long time here.
