@Serverlux Hi Sascha, thank you for this opportunity (I'm still waiting for the VPS test to begin (Image)

ICANN is a non profit organization which is maintained by their own board and works together with verisign on the DNS system.

Redundant DNS Clustering

Google DNS materiality?

• Self manageable Reverse DNS (rDNS) control

Do not host nameserver on the same server hosting websites. Well, at least get 1 or 2 separate server for nameserver redundancy. A cheap small VPS on different location would do, install cPanel DNS On

You might setup a local DNS server that does that "translation" for you, however port and protocol still have to be specified by your family members.

Yeah I was actually using it to test the network and discovered the DNS issue as a result of that testing...something wasn't loading so I ran the trace and when I saw it hop through California for a s

Tracery is not a DNS checking tool. It's a network diagnostic tool. Would've more interested to know what nslookup and dig have to say.

DNS caching. (Image)

Ultimately, relying on dns server to determine whether to send your master app server IP or secondary app server IP in the dns response will not provide you with immediate fail-over due to:

If both IP addresses are provided in DNS, the browser is free to (and will) arbitrarily choose between them. There is no priority on A records like there are on MX records.

it seems like RR DNS is the best option for me. But, I am not looking for Load balancing but, fail-over. Are there any DNS providers that, when you specify more than one IP, it sends the IPs in the

Your best option would be to go with DNS round-robin as I explained above, I am unaware of other methods that offer close to immediate fail-over.

seems like DNS caching may make DNS failover services not fully HA... right?

You can also use DNS provider who monitors the state of application and will return only IPs of healthy nodes.

When a DNS request is made, if DNS round-robin is setup properly it should return both your reverseproxy ip to the browser. you can test your dns setup by running this in linux console: dig @8.8.8.8 d

@hbjlee17 , thanks, so if there are 2 reverse proxies with R-R DNS, what happens if one of the proxies goes down?
