Notes
The effective search range for the drive was about n = 500000 - 750000.
Primes were reported in Free-DC's Prime Search thread here.
A private search was done for n = 485000 - 500000 before the drive started. Primes were reported at top-5000 primes and in the above thread but are not considered part of the drive.
Primes were omitted in the above thread for n = 669500 - 700000 & n = 704500 - 743000 but were reported at top-5000 primes. These primes are considered part of the drive.
The suspended date is the date that the server was allowed to run dry as shown in the final 3rd drive post.
