Hi all,

I am very interested in this product but not sure if it can help us in our situation. We kind of have the opposite scenario. We have one server but two different network connections coming in from two different ISPs for failover. So if one ISP goes down, the other can take over. We were looking into the DNS round-robin solution but we see its not failover proof which brought us to your website.

So instead of having multiple servers and one ISP coming in, we have multiple ISPs coming in to one server. The trick we are trying to resolve is how to get two different networks to failover to each other.

Any ideas how we can do this and/or if this product will handle it?

I appreciate any and all suggestions and comments!

You can do this if you place Simple Failover "outside" / somewhere else on the Internet.
See http://www.simplefailover.com/scenario5.aspx

For the upcoming v. 2, we are considering adding some new features making it possible to monitor multiple connections from the inside.

Sincerely,

This looks good! I do have a follow up question though. What about the issue regarding up to 24hrs for the public DNS servers out on the internet to populate/update?

Thanks again for the rapid response on my first post. I appreciate it.

The lenght of time it takes to update DNS records depend on the TTL (time to live) value.
This is often set to 24 hours - but in this setup - you will use a much lower values - such as one minute.
For more on this see http://www.simplefailove.../outbox/dns-caching.pdf
