We have noticed multiple storage arrays are having some issues, we are checking it.
There were a couple customer VM down due to this but are up now or in chkdsk.
We are also preparing a new server and will be migrating all off of the node as it seems there could be an issue in the backplane making it drop drives.
We will be mailing clients on this server of plans for the next 24-48 hours to move their VPS to a new node. We have all but one up (and it is up but in chkdsk) now. We will attempt to do this on a planned basis but will have a tight timeframe to do the moves so that we can ensure the stability for everyone.
