Check DNS, Urls + Redirects, Certificates and Content of your Website


Info: Problems with 3.048.289 Letsencrypt certificates (378.325 accounts). They must be revoked (revocation starts 2020-03-04 20:00 UTC) - see Revoking certain certificates on March 4. Update 2020-03-07: Good news: Mass-revocation is canceled.

This tool: A check (SerialNumber) is added. Letsencrypt has published a list of critical SerialNumbers, this list is checked. See the part "9. Certificates". If there is a warning, renew that certificate and replace the current certificate.

Info: The Xml-split has triggered some hidden bugs. Now it looks ok.
If root or the top level zone isn't validated, it's buggy.

7. Comments


1. General Results, most used to calculate the result

Aname "nthos.com" is domain, public suffix is "com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services"
Agood: All ip addresses are public addresses
Agood: No asked Authoritative Name Server had a timeout
Ahttps://nthos.com/ 45.79.181.36
302
https://nthos.org
correct redirect https to https
Agood: destination is https
Agood - only one version with Http-Status 200
Agood: one preferred version: non-www is preferred
Agood: every https has a Strict Transport Security Header
Agood: HSTS max-age is long enough, 63072000 seconds = 730 days
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
Ehttp://nthos.com/ 45.79.181.36
302
https://nthos.org
Wrong redirect one domain http to other domain https. First redirect to https without new dns query, so the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

2. DNS- and NameServer - Checks

AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns-cloud-a1.googledomains.com,ns-cloud-a2.googledomains.com,ns-cloud-a3.googledomains.com,ns-cloud-a4.googledomains.com
AGood: Nameserver supports TCP connections: 8 good Nameserver
AGood: Nameserver supports Echo Capitalization: 8 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 8 good Nameserver
AGood: All SOA have the same Serial Number
Agood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates

3. Content- and Performance-critical Checks

Fatal: All checks of /.well-known/acme-challenge/random-filename have a redirect, destination doesn't have the random filename. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
https://nthos.org
200

Warning: https result with status 200 and size greater then 1024 Bytes without GZip found. Add GZip support so the html content is compressed.
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
AGood: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
