ClouDNS vs Bunny
Hi All,
Current ClouDNS user here. Revisiting DNS hosting for my roughly 30ish zones. Overall I have been happy with ClouDNS, but the one point of contention I have is how long it takes for them to propagate DNS changes across all of the PoPs.
Using ACME and DNS-01, I have to allow a minimum of around 3 minutes, sometimes closer to 5 minutes, before validation can safely happen. I finally decided to test it instead of just complaining about it.
I compared ClouDNS against Bunny DNS using unique TXT records created through each API and checked them locally and from several regions worldwide.
Bunny, over 10 rounds, had a median authoritative propagation time of about 3.6 seconds and a worst case of 5.5 seconds. Worldwide authoritative checks were 120/120.
ClouDNS, over 5 rounds, had a median of about 27 seconds and a worst case of 35.5 seconds just from my local perspective. More concerning, after the local authoritative servers were returning the new record, a number of ClouDNS anycast locations around the world were still returning NXDOMAIN. Worldwide authoritative checks were only 72/120 at that point.
So that pretty much explains my ACME propagation delays.
Bunny is looking interesting. The DNS product has matured a lot since the last time I looked at it, with a proper web UI, DNSSEC, API support, etc. My hesitation is reliability. ClouDNS advertises around 65 DNS PoPs while Bunny has 36+ dedicated DNS PoPs, and Bunny has had a few notable DNS/platform outages over the last couple of years.
On the other hand, Bunny also seems much more transparent about outages, so it is hard to know how much weight to give that.
What is everyone using these days? Anyone using Bunny DNS for production? Any other ClouDNS users seeing the same slow propagation?

I use Bunny for DNS, CDN and some storage, it's great in my experience.
Have been loving Bunny. No issues had yet and support is insanely fast.
I use Bunny for PTR for my IPs, no problems and good service. I've never used Cloudns.
