We support two different DNS Failover methods. Sequential and Round Robin. Sequential Method: This method uses the server IP addresses one by one in the order they are entered. That way, you always have one IP address announced for your ‘A’ record, which is considered a primary server. Should that server go offline, the failover […]
Total Uptime’s DNS failover works by constantly monitoring at least two servers using any number of fully customizable monitoring tests that you create. It allows you to send traffic to those servers via one of two methods. (1) You can use Round Robin to send traffic to all of your available servers, or (2) you can send traffic […]
The DNS Failover Service determines a server is down based on the monitoring type you’ve selected and configured. For example, if you’ve created a PING monitor and assigned that to your server, as soon as it stops pinging and exceeds the test “interval” and “retries” values you’ve specified, it will be considered “down” and subject […]
Yes, our DNS failover service was designed to easily support manual failover. Often customers wish to test their failover site on a periodic basis, or they wish to redirect traffic during a maintenance window. To do this within the portal, open up the Failover Entry, and simply uncheck the “Active” checkbox as shown below. This will immediately […]
When implementing a failover solution, the most common questions we receive are: How can we architect a failover solution for our application? How quickly can we failover from the primary site to the secondary site? How quickly can it fail back when the primary comes back online? Is there a way to prevent automatic failback […]
In the early days of the Internet, humans and other computers located the few massive interconnected computers the same way: by their numeric Internet Protocol (IP) addresses. Soon, the impracticality of memorizing all these numbers became obvious and a rudimentary naming scheme was developed. A central repository of names and their associated IP addresses was […]
Method: POST URI: /ALF/LoadBalance/Policy This method creates a new load balancing profile that you can then attach to a Pack. It requires the following information: Field Required data *Name The name of the profile. E.g. “Profile #1” *Method The […]
Method: POST URI: /CloudDNS/Failover/Pool This method creates a new failover pool. It requires that the following information be posted in order to successfully create the domain: Field Sample data Name e.g. “My first failover pool” IPType “ipv4” or “ipv6” […]
Don’t want to read the manual? Watch the video instead! Failover Pools are lists of one or more IP addresses (IPv4 or IPv6) that can be assigned to A or AAAA records to automate record changes based on certain monitoring criteria you specify. For example, you may have a failover pool that contains the IP […]
If you are a network administrator, you really want to get a handle on your network. But even laymen sometimes need to figure out what’s going on. There are some basic tools that will help you do that. Let’s have a look at some simple pieces of software that can be accessed from nearly any […]
