Hypergrid Business has an article up on problems over at OSGrid, my favorite OpenSim grid. It seems that Tuesday or maybe Monday some time the asset servers went down. The word coming from OSGrid peeps is that the RAID drives in the asset system failed.
The content of the asset servers will have to be restored from backups. There is typically a huge amount of data in an asset system for a virtual world. So, this will take some time. They are giving no estimates of when they think OSGrid will be back online.
Not knowing how big the data collection is for OSGrid or what the backup media is or how it is connected we can’t guess at the time needed to move the data. But, it could be days, hopefully way less.
