Yesterday a new post appeared on OSGrid News: osgrid update for 2015-02-16.
The assets have been recovered and loaded into the asset servers. Now the network configuration is being setup to put the servers online. There is no ETA for completion of this work.
There are discussions ongoing about how the OSGrid will be restructured. They say no drastic changes. But, there is some plan to modernize some aspects of the grid, whatever that means.
The next update for users is planned to be 2/22 or 23.
