While speed and scale are all critical focuses of your online infrastructure (and rightfully so) — availability of your web-properties rules the roost amongst any company leveraging the Internet for revenue or productivity. The importance of network availability and continuous monitoring of your endpoints must be a priority.
Active Failover with Dyn Managed DNS is providing businesses large and small the ability to ensure their online infrastructure is always available. Downtime is evil. Availability, Speed, and Performance are winning — and it’s much easier to setup than you think.
Having the ability to swiftly and dynamically route traffic away from a dead IP is an easy but extremely impactful business solution. Active Failover should matter to you because loss of revenue and/or productivity is unacceptable. You want eyeballs on your endpoints 24/7, and you are sick of managing proprietary mountains of hardware to do it.
What this means to you is that if you have a data center, server, or even a hosted VPS failure, Active Failover enables your website to stay up and running — all while making the experience seamless. When an outage is detected, your traffic is automatically routed to an alternate endpoint that you have pre-configured. Compatible with both IP addresses for traditional setups and CNAMEs for cloud hosting setups, Active Failover on Dyn Managed DNS gives you more options for your endpoint selections.
Let’s quickly break down the 7 easy steps to setting up your very first Active Failover.
- Start off by viewing the Services section and clicking the Add a New Service dropdown. From there, select Active Failover.
- If your hostname already has an A or CNAME record, the Address line will be populated. If not, fill in the the address/location you want to monitored.
- Select one of the five monitoring protocols under the Health Monitoring section, most commonly our HTTP option. Be sure to click on the Interval drop down to select the appropriate interval you’d like the probes to be sent at.
- Three of Dyn’s closest probes will be sent at whichever interval you select. If two of the three probes detect a failure, the Retry cycle will commence.
Okay, we are literally almost done!
- Select the amount of Retries by clicking the drop down.
- Side note; there is a 10 second window between each retry, not another whole interval!
- If at the end of the Retry Cycle your IP or CNAME is confirmed down, all your traffic will be routed to the Failover Address you assigned in the Failover Handling section.
- By default, once your monitored primary address is detected to be back up and running, your traffic will be routed back to your primary site address.
- Optionally, you can choose to keep traffic going to your Failover Address until manually activated. Just select the checkbox under the Failover Address, and when you want to force traffic back to the monitored address, simply click the “Recover Now” button, located at the top right of the page.
It’s Your Move
Ask yourself, your peers, and your teams these questions:
- How much would downtime cost our business?
- How do we currently monitor your servers?
- Who oversees our ability to control our traffic?
- How much sleep would I get back if I had Active Failover with Dyn?
Active Failover is just one example of how we are providing companies impactful Internet Performance solutions.
