DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "i77daotf1hrr48e96kppg6qt7fjjua34" between the hashed NSEC3-owner "i77d4nth7nnjca0omef6indcusr34s70" and the hashed NextOwner "i77dedntv6sut513nodrnfiq766a5qb8". So the parent zone confirmes the not-existence of a DS RR.

7. Comments


1. General Results, most used to calculate the result

Aname "surf-cloud.org" is domain, public suffix is ".org", top-level-domain is ".org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)", num .org-domains preloaded: 10357 (complete: 276475)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: surf-cloud.org has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: surf-cloud.org has no ipv6 address.
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
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)
Ahttp://surf-cloud.org/ 45.136.57.232
308
https://surf-cloud.org/
Correct redirect http - https with the same domain name
Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain surf-cloud.org, 1 ip addresses.
BNo _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.surf-cloud.org

F

Bad: default-src with "*" or a scheme found. That allows too much, don't use such a definition. connect-src
A

Good: default-src without 'unsafe-inline' or 'unsave-eval'. connect-src
A

Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.
A

Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
A

Good: base-uri directive found. That limits the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A

Good: object-src only with 'none' or 'self' found, no scheme, no other urls. That blocks object / embed / applet - elements.
F

Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
F

Critical: script-src with * or a scheme found. Never allow wildcard - sources.
A

Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
A

Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.

200

Warning: Not existing ACME-file, but Server sends 200, not 404 or redirect. May be a problem creating a Letsencrypt certificate. Checking /.well-known/acme-challenge/random-filename - a http status 404 - Not Found - is expected. If your server sends content and a http status 200, the validation file (87 bytes, token, dot and the hash of the public part of the account key) may be invisible, so Letsencrypt can't validate your domain. If it is an application that sends this content, perhaps create an exception, so /.well-known/acme-challenge sends raw files. Or create a redirect to another domain and / or port 443, but your Letsencrypt client must support such a solution. Certbot: Use webroot as authenticator - https://certbot.eff.org/docs/using.html Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.

AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.

Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 2 script elements without defer/async.

AGood: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 8 external CSS / JavaScript files found
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 8 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 8 complete.
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
