Three days ago I was forced to come back to ITMO (at midnight!) to turn on the server. I was just happy that the night security at the university understood everything and I got into the server room without any issues. It seems the server was overheated and and shut down. Today, I and _kun_ are planning to update a thermal grease in it. We have not done this before (but I watched the video on YouTube). Wish us good luck!
