Website infrastructure toolkit
Tools for diagnosing website, DNS, email and performance problems.
A practical resource hub. Bloggingfy links to established external tools where we do not yet provide our own utility, and clearly labels planned Bloggingfy tools.
DNS & Domain Tools
Use these when a domain does not resolve, nameservers look wrong, records have not propagated or ownership details need checking.
- ICANN Lookup External — registration and public domain data.
- Google Admin Toolbox Dig External — inspect A, AAAA, MX, TXT and other DNS records.
- WhatsMyDNS External — compare DNS propagation across locations.
- DNSViz External — visualize DNS and DNSSEC problems.
Website & WordPress Tools
Built into WordPress
Start with Tools → Site Health in WordPress. It surfaces configuration, REST API, update and server issues without installing another diagnostic plugin.
External diagnostics
- PageSpeed Insights — Core Web Vitals and lab diagnostics.
- W3C Markup Validator — HTML validation when rendering breaks unexpectedly.
- WP-CLI Command Reference — official command documentation for controlled WordPress maintenance.
Email & DNS Authentication Tools
Useful when business email lands in spam, SPF fails, DKIM is missing, DMARC reports look confusing or MX records are not correct.
- Google Admin Toolbox Check MX External — mail exchanger and common domain checks.
- MXToolbox External — MX, SPF, DKIM, DMARC and blacklist lookups.
- Mail-Tester External — practical deliverability checks for a test message.
Website Migration Resources
Before the move
- Take a verified files + database backup.
- Record current DNS, email and SSL settings.
- Lower DNS TTL only when the migration plan genuinely requires it.
During and after
- Test the destination before changing DNS.
- Check internal URLs and mixed-content references.
- Verify forms, email, redirects, analytics and indexing after cutover.
Hosting & Performance Resources
- PageSpeed Insights — Core Web Vitals and performance opportunities.
- WebPageTest — waterfall, filmstrip and repeat-view diagnostics.
- Cloudflare Speed Test — connection quality and network measurements.
- Security Headers — inspect common HTTP security headers.
Future Bloggingfy Free Tools
This section is intentionally structured for utilities we may build later. These are roadmap slots, not live tools today.
DNS propagation checker
Planned: a focused way to compare essential DNS records and explain mismatches.
SPF / DMARC explainer
Planned: translate authentication records into plain-English checks and likely fixes.
