Cloudflare Zero Trust DNS Script Fails to Resolve CNAME to IP
A shell script for updating Cloudflare Zero Trust DNS policies fails when the target domain is a CNAME rather than an A record — it passes the canonical name string instead of resolving it to the underlying IP address. This causes the Cloudflare API to reject the input with an invalid CIDR error. The issue affects network administrators using CNAME-based failover setups for multi-WAN configurations.

Shopify Blocks Domain Nameserver Changes, Trapping Users on Their DNS
Shopify prevents merchants from changing nameservers on domains registered through its platform, making it impossible to migrate DNS control to providers like Cloudflare. This forces merchants to use Shopify DNS even when they need features like DDoS protection, advanced routing, or CDN control. The restriction is perceived as anti-competitive and degrades user trust in the platform.

Intermittent DNS Failures Break Alpine-Based GitLab CI Jobs
A developer hits an intermittent 'DNS: transient error' installing packages in an Alpine-based GitLab CI job, even though a rerun without changes succeeds and the package URL is reachable locally. This points to unreliable DNS resolution inside GitLab runner containers, a hard-to-diagnose class of CI flakiness.
