Root Flattening CNAME accuracy simple test

Table Of Contents

Summary

I ran a test through App Synthetic Monitor about how IP resolution accuracy about plain cname and root flattening cname in CloudFlare. The CNAME needing to be resolved is a balancer hostname in PerfOps.

It seems to me that CNAME flattening on CloudFlare is far from accurate on IP resolution. Considering both of my IPs are behaving differently in every regions, I switched the site from root domain to www domain. Root domain looks pretty but on Cloudflare my best bet is subdomains like www when it comes to things like load balancers.

Maybe that's one of the reasons why gitlab redirects its root to about.gitlab.com. (But that's not the case for Github).

Anyway if I want accuracy while sticking to root domain, then I might have to switch to another dns service.

2019-06-18: My future go-to DNS service: NS1, Route 53. They both support GeoDNS, which solves what I need for root domain. The DNS of the domain has been changed to NS1. Now the domain just needs time for DNS propagation. They have a free plan with 50k query limits. Once I surpass that limit, I will consider switch to Route53 'cause it's much more cost-efficient.

Result Table: Accuracy

Bold IP means mismatch.

Results:

Plain CNAME works like charm without any IP mismatch from the original load balancer.

CNAME Flattening results in 27 IP mismatches, the IPV6 cache (old resolution, also mismatches) doesn’t count.

Result Table: When the load balancer hostname points to different IPs or hostnames worldwide

You might say the result says nothing and this can happen in subdomain if I change the IP in balancer hostname. So I made a further test.

Point the balancer hostname to a single hostname resolved to itself

I turned Proximity on to make the IP same everywhere (a buggy feature in Perfops).

It seems everything works out now whether it’s Root Flattening or Plain CNAME. The IPV6 is due to me setting fallbacks to a hostname resolved to either an IPV4 or IPV6.

At least the root Flattening is made for hostname resolved to a single host.

This test also proves that no such things like external cache affects the results too much.

Changing the balancer hostname back to the original state

Bold IP means mismatch from original balancer.
I ran the tests several times to make sure the result is as final as it could.
CNAME Flattening results in 14 mismatches, while plain CNAME works well.
And the mismatches are still happening now. And from my experiuences recently, they could happen forever with some new mismatches.......The result can be different each time.
