Rake search of diagonal Latin squares: 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.
