For high availability of its web services, Service Objects maintains a failover backup data center that is identical to our primary data centers.
The failover data center is designed to increase the availability of our web services in the event of a network or routing issue. We employ two primary data centers and one backup data center.
Service Objects' primary data center hostname is: ws.serviceobjects.com and our backup data center hostname is wsbackup.serviceobjects.com.
FAILOVER MAY NOT BE INSTANT, THEREFORE:
Integrate a failover configuration into your application. In the unlikely event that the primary data centers do not respond in a timely manner.
Do not code your application to a specific IP address. Using our hostnames will provide you with the most amount of uptime. If your egress traffic is restricted by firewall or routing rules, please ensure the following IP addresses are whitelisted: 220.127.116.11, 18.104.22.168, 22.214.171.124
You can also abstract the actual hostname into a configuration file, in order to simplify the process of changing hostnames in an emergency. Even in the case where your application handles failover logic properly, an easy-to-change hostname would allow your application to bypass a downed data center completely, and process transactions more quickly.
For most clients, simply updating their application to use our backup data center hostname should immediately restore connectivity. Your existing DOTS license key is already permitted to use our backup data center and no further actions should be needed.
In the unlikely event of a significant network failure at both of our primary data centers, we will redirect our DNS record to temporarily point to our backup data center. In this case, no changes are required on your side.
