Coming up on a big milestone here. From Wikipedia, 2008:

After Batalov's latest, the count under 1M is down to 9211, so just 11 more to make it to a round century, or another 14 to make it 250 terminations since we started this project. Very nice!

Unhappy A rather embarassing ECM miss

After 2 weeks spent sieving 572000:i3128, I woke up to this:

Got a downdriver for 613068:i705 (unreported, to avoid poaching), 128 digits. Let's see how low it goes... I put 4 cores into it. (sorry kracker :P)

Short living. It went back to the "trend line" after a small "vulcano pattern". I still keep it reserved, to be clear.
