57-bit DONE after 8 days!
The found S actually had 58 leading bits of 0 (57 were enough).

Server logs...
And total running stats....
So that was around 59212 trillion signatures.
Total costs: 110 $
This was emotional. Up to the lucky hit, the best results that I got were all 54 bits or less, and I was starting to wonder whether the risk is worth it. Then 58 hit hard to compensate for the unexpected bad results

Did you create the repository for the application used?
