Intermitent storage connection problems are affecting Virtual Machines, which become randomly unavailable for a while then may become responsive again.

Update 26/9 08:00: the situation is slowly improving and getting more stable as the stress on the primary storage cell is being reduced (VM storage partially migrated to other storage cells, I/O intensive services such as antivirus scans disabled etc.), but not resolved yet.
