CDN & Delivery

Action

No CDN detected

FIX

No CDN detected

A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

No CDN detected

Consider using a CDN to improve global delivery speed and reduce origin load.

IPv6 Readiness

Action

No IPv6 support

REVIEW

No IPv6 support

No IPv6 (AAAA) records found

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

No IPv6 Support

About 40% of internet users have IPv6. Consider adding AAAA records.

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

Why this matters

No AAAA records — same impact as 'no IPv6 (AAAA) records'; IPv6-preferring clients pay extra latency falling back to IPv4.

URL Variants

REVIEW

www/non-www, trailing slash, HTTP→HTTPS

Both www and non-www versions serve content

HTTP correctly 301-redirects to HTTPS

DNS Records

1 A records, 132 ms lookup

PASS

1 A records, 132 ms lookup

Resolves to 1 IPv4 address(es)

Got: 20.119.136.3

Single A record — no DNS redundancy

Multiple A records provide failover if one server goes down.

No IPv6 (AAAA) records

3 nameserver(s) configured

Got: dns-auth-02.oit.duke.edu, dns-nc1-01.oit.duke.edu, dns-auth-01.oit.duke.edu

1 mail exchanger(s) configured

CAA records not checked

CAA record lookup requires a specialized DNS resolver. This check will be available in a future update.

CAA	Lookup not available with standard resolver

Resolved in 132 ms

Multiple A records provide failover if one server goes down.

Why this matters

Single A record means a single point of failure — if that IP goes down, your site is unreachable until DNS TTL expires.

Learn more ▾

Add multiple A records for round-robin failover, or use a managed DNS provider with health-checked failover (Route 53, Cloudflare, NS1). Short TTL (60-300s) lets clients recover faster on outages.

Crawlability

PASS

robots.txt is present

Got: 10240 bytes

sitemap.xml is present

sitemap.xml is valid XML

sitemap.xml contains 2 entries

Sitemap index with 2 child sitemaps

robots.txt does not reference a sitemap

Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

Why this matters

robots.txt omits Sitemap: directive — crawlers must fetch /sitemap.xml by convention; reliable but missing the explicit hint.
