[Minecraft@Home] Maintance Saturday 2026-05-23 | 9 AM UTC

Hi all,

Heads up: The Minecraft@Home infrastructure will be down for maintenance tomorrow, Saturday (May 23rd) starting at ~ 8:30 AM UTC, for some hardware and software updates.

Downtime will last for a few hours. I can't give an exact ETA, but I'll do my best to get everything back up and running as fast as I can.

Cheers,
Philipp

[SRBase] cable provider down

All services stopped as of May 7, 12:00 UTC+2.

This was the first long major outage since years.

Not a good start for the Pentathlon and certainly not how it was planned.

If the current deadline proves insufficient, it will have to be extended.

Let me know if you have problems with deadlines or other things.

I hope for no more issues on provider side.

Thx for your understanding and support!

[RakeSearch] RakeSearch recovered after technical problems

Dear participants,

thank you for your patience while we were recovering the project. There had been a failure of both SSD discs in a mirror. hoarfrost then did a good job on updating the server and recovering as much data as possible. We had backups of the most important data but not a total backup of everything. I recovered a large part of the forum (sadly excluding the private threads belonging to teams); some particular threads or posts could not be recovered. We hope it does not cause too much inconvenience.

Most of the results you reported before the maintenance have been received, and the credit had been assigned. There may be still some technical glimpses but overall the project is working!

Thank you for participation and the computing power you provide us.

Natalia

[Amicable Numbers] The search up to 10^21 is finished

After more than 6 years, the BOINC project to find all amicable numbers up to 10²¹ is finished!

There are 4,810,863 21-digit amicable numbers, and 4,661,814 (96.9%) of them were found by BOINC volunteers. More than 60 million WUs were created and crunched through over the years.

Congratulations everyone and thank you all for your participation!

There are no plans to run the search up to 10²² at the moment - it will take more than 60 years, which is impractical. If, and that's a big IF, a new more efficient exhaustive search method is discovered in the future, then it will make sense to start the project again.
