There was a problem on the data pool.
We put the data in readonly in order to find a solution.
Update(s):
Date: 2011-12-31 04:07:40 UTC New accounts will be available to allow continuity of backups.
A mailing will be sent to affected customers.
The original data remains accessible on readonly.
Date: 2011-12-23 19:51:14 UTC After several attempts, we still have a kernel panic when we try to reactivate thr writings.
We're trying an upgrade and a pool analysis.
