To be covered under the\nnon-critical applications [SLA](/network-connectivity/docs/interconnect/sla) (99.9% monthly uptime\npercentage), you must build your network according to this topology. The 99.9%\navailability configuration requires two Cloud Interconnect connections\nand two VLAN Attachments in a single Google Cloud region.\n\nYou can achieve a 99.9% availability configuration with\nDedicated Interconnect or Partner Interconnect by\nusing the following documents:\n\n- [Establish 99.9% availability for Dedicated Interconnect](/network-connectivity/docs/interconnect/tutorials/dedicated-creating-999-availability)\n- [Establish 99.9% availability for Partner Interconnect](/network-connectivity/docs/interconnect/tutorials/partner-creating-999-availability)\n\nTo help you achieve a 99.9% availability configuration, we recommend that you\nuse interconnect connection groups. These groups provide you with information\nabout whether your configuration meets the requirements for your intended level\nof availability. For more information about interconnect connection groups, see\n[Resiliency and SLA options](/network-connectivity/docs/interconnect/concepts/overview#sla-options)."]]
