We are a few days away from launching a new service called failover hosting.
Our failover hosting will provide you with a higher up time as it will provide you with a minimum of 2 accounts in 2 separate data centers. The service includes site monitoring to ensure your site is up, if your site is detected as being down your DNS will be updated automatically to update to use the second account (and others if you have more then 2). This service also includes rsync for your files and replication for your databases. Our failover hosting can scale up to 5 accounts on 5 separate servers in different data centers.
This can now be purchased on our main site here.
If you have any questions about this contact our sales staff at email@example.com.
