I use Cloudflare free DNS for 2 different domain names. One of these I use DNS-O-Matic to dynamically update the IP address when it changes (DNS-O-Matic is a DDNS updater that can update multiple places at once). The other domain has a hardcoded static IP address.
About half an hour ago, I was using the domain with the hardcoded IP, and all of a sudden it starts redirecting me to the IP address for the other domain.
I checked the logs at DNS-O-Matic, and it had triggered an update with Cloudflare at the exact the same time this started happening.
I logged into Cloudflare, and sure enough the IP address for the hardcoded domain name had changed. I manually changed it back and disabled DNS-O-Matic for the time being just to be safe.
I’ve been using this DNS setup for years without change, so I suspect there was a glitch with either Cloudflare or DNS-O-Matic. I’ve emailed DNS-O-Matic to see if they can check their logs.
At this point, I don’t know where the glitch occurred. It could be one of two places:
- Cloudflare. When DNS-O-Matic sent an IP update to Cloudflare, it was messed up on Cloudflare’s end and updated a domain it shouldn’t have.
- DNS-O-Matic. When it sent an IP update to Cloudflare, it was sent to the wrong address.
Is there anyway for me to know where the problem occurred? Has anyone else experienced any DDNS problems with Cloudflare today?
