Depending on the impact and source of network issues, there are several solutions.
If network issues are in the customer network provider, there is the possibility to install a master-slave infrastructure with a local copy of Athento. Depending on how frequent network issues may be, the slave local copy may be used only for reading information.
If network issues are far from the customer network provider, a different datacenter will be used to route through a different link.
Take into account that the service provided by Athento already provides a cluster with nodes in at least two different datacenters.
