I had orange-cloud A records for domain cdn-staging.kamaitachi.xyz until recently. I tried changing this record to dns only as I wanted to debug some concerns I had relating to caching on my origin server. After 20-30 minutes of the nameservers still responding with Cloudflare IPs I tried deleting the record entirely. It has now been another 20-30 minutes and the nameservers are still responding with Cloudflare IPs (104. and 172.). I am at a loss.
