I don't look at my miners very often, I'm not running enough Hashrate to get excited about.
I saw one miner off line this morning . When I signed in I aw my "BestShare" at 18446744072376070000 and thought "Did lightning actually strike?"
You know 18 quintillion is a pretty good share. Then I notice the miner is not restarting properly so I guest it was just the dying gasp of the old T15.

It would have been nice though.
