Hello Chris,
I did explain you the situation over live chat. Your sites are on Puma as well. This server's home partition is currently in Read-Only mode. This is being worked upon. The sites will be back online soon.
If you are looking for higher plans where you have more isolation in terms of issues and usage, then we do have
VPS plans in place. These not only give you root access, but also WHM along with Virtuozzo Power Panel to manage and perform administrative tasks to the level of being able to restart and reinstall OS yourself for your VPS.
If you have corporate customers banking on you, then a VPS would be a better option. Though expensive compared to the shared hosting plans, it will give you better performance levels.
