I would suggest you to withdraw all your funds there once the "maintenance" is complete, 2 days "maintenance" isn't normal.
It is possible that :
1. "Someone" exchanged significant amount of Bitcoins to LR $ in various "mini" LR account after the "operation" is successful
2. Liberty Reserve doesn't have enough massive "reserve" to cover that up
3. Liberty Reserve goes into "maintenance" mode for 2 days until this pirate incident is clear
Note :
LR is hacker's preferred payout choice during bitcoinica and other bitcoin "hack".
