Firts, my apologies for the unexpected shutdown of the Rijndael Project server.
The last week, concretly the 2 of december, the server was shutdown suddenly and without any logical reason and has remained offline for 7 days. I thought it was a hardware reason (take into account the server is an older computer), and I was right, but I don’t had time for fix it in those days and i’m was outdoors. Therefore, I couldn’t solve until now (this was the principal reason 
The problem was originated in the power supply, and was caused for a bad soldering of the improvised heatsink/fan of the PS and this generated an unstable voltage.
And finally, as usual, some pictures on the repair process (I also clean the dust)
Now, all of the services are up and running!
I hope it never happens again until the server change.
