Yesterday at about 10:09 AM UTC there was a power outage in the computing center where our servers are located.
The servers were back online (accessible from the Internet) at about 12:35 PM UTC - a downtime of about 2:20 hours.
After powering up several systems were in failure mode and not fully recovering on their own.
It took us another hour to bring CL and related sites back up again.
Please accept my apology for this service outage.
We are working on alternative solutions.
