The problem occurs sporadically, so we cannot give the all-clear just yet.

The source of the problem has been identified, and corrective measures have been implemented.
Even though the situation appears to be stabilizing, it is still too early to give the all-clear. We are closely monitoring the situation.

Initial investigations have revealed that several virtual machines are affected and are currently unavailable.

Unfortunately, the virtual web servers are currently unavailable; the
problem has been identified, and we are working on a solution.
