Today, at 12:03:14, Orfeo suffered from a power outage. It was restarted quickly, and Hivane/Alionis people assisted us efficiently. Unfortunately, a kernel bug  prevented the machine from booting correctly. A hardware problem might additionally be possible, even if not critical. Late in the afternoon we were able to diagnose the problem and work around it.
Moreover, webmail.dc.o and webdesk.dc.o were unusuable until this evening due to a software upgrade problem (unrelated to the power outage).
In the evening, we finished checking all services, and since then everything should be all right. Do not hesitate contacting us if you find an issue.
