Addressing these will not only enhance the readability and reliability of our HPC documentation but also significantly improve user satisfaction and the overall SEO performance of our resources. Think of it this way: every broken link is a potential user lost, a piece of information inaccessible, and a small dent in the credibility of our platform. By methodically reviewing and resolving these issues, we empower our users with seamless access to the critical information they need to succeed with VSC resources. This proactive approach to link management is not just about fixing problems; it's about continuously enhancing the value and accessibility of our educational and support materials. We understand that our users rely on accurate and current documentation, and this report is our commitment to delivering just that. Let's explore the specifics of what our link checker found and how we plan to transform these insights into actionable improvements for your benefit.

Decoding Common Link Errors: What Went Wrong and How to Fix It

File Not Found (ERROR 404): The Missing Pages of Your HPC Documentation

The most common and often the most frustrating error users encounter is the dreaded File Not Found, or a 404 error. This happens when a link points to content that simply isn't there, has been moved, or has been deleted without a proper redirect. For our hpcugent and vsc_user_docs, these errors are particularly disruptive, as they can prevent users from accessing crucial setup guides, troubleshooting tips, or examples. Our report highlights several instances of these internal file:/// errors, indicating that some of our relative paths within the documentation are no longer valid. For example, in mkdocs/docs/HPC/account.md, links like <file:///home/runner/work/vsc_user_docs/vsc_user_docs/mkdocs/docs/connecting> and related sections (#generating-a-publicprivate-key-pair, #open-a-terminal, #hpc_policies, #linux-tutorial) are reporting File not found. This suggests that the target files or specific anchors within them either don't exist at the referenced path or have been renamed/restructured. Similarly, mkdocs/docs/HPC/alphafold.md shows multiple errors pointing to {{readme}} and running-alphafold, hinting at templating issues or incorrect file references that prevent users from reaching essential AlphaFold documentation. These broken internal links create significant friction for users trying to learn about account management, connection procedures, or specific software applications. To address these critical documentation issues, we need a systematic approach. First, it involves meticulously reviewing the source files (account.md, alphafold.md, connecting.md, etc.) and comparing the referenced paths with the actual file structure. We must correct any typos, update outdated paths, and ensure that all internal anchors (#section-name) accurately reflect existing headings. For content that has been permanently moved, implementing 301 (permanent) redirects is essential to preserve link equity and guide users seamlessly to the new location. Regular internal link audits are paramount to catch these errors before they impact user experience. By fixing these 404s, we can dramatically improve the navigability and reliability of our VSC user documentation, making it a more dependable resource for everyone.

Access Denied (ERROR 403 & 401): Forbidden Zones and Unauthorized Access in VSC Documentation

Beyond just missing pages, our link checker also flagged instances of access denied errors, specifically 403 (Forbidden) and 401 (Unauthorized) status codes. These errors indicate that while a link might point to an existing resource, users are being blocked from accessing it, often due to permission issues or internal network restrictions. This can be particularly confusing and frustrating for users who expect seamless access to all linked resources within the hpcugent and vsc_user_docs ecosystem. Examples from the report include https://login.hpc.ugent.be/ returning a 403 error in mkdocs/docs/HPC/getting_started.md and infrastructure.md, and https://linux.die.net/man/1/setfacl also showing a 403 in manipulating_files_and_directories.md. A 401 error was reported for a SharePoint link in mkdocs/docs/HPC/sites/hpc_policies.md. These types of errors suggest a few potential root causes. For external links like those to linux.die.net, it might be that the external site has implemented new security policies or geo-restrictions, or perhaps their server configuration has changed. For internal links or links to sensitive HPC resources such as login.hpc.ugent.be, a 403 error could indicate that access is intentionally restricted to certain IP ranges or authenticated users, which might not be correctly handled by the link checker's context. Alternatively, it could point to a misconfiguration in our documentation where a link is publicly exposed but the resource itself requires specific authentication or resides behind a firewall. The 401 error from the SharePoint link strongly suggests an authentication challenge, meaning the resource requires a login that the automated checker cannot provide. To resolve these access issues and improve VSC documentation accessibility, we need to investigate each instance. For restricted internal resources, we must ensure that such links are either clearly marked as requiring specific access, or that the documentation guides users on how to obtain the necessary permissions or log in. For external links, we'll need to verify if the content has moved to a new public URL or if an alternative, publicly accessible resource can be provided. In some cases, if the content is truly intended to be private or internal, then the link should be removed or made conditional. Regularly reviewing access policies and ensuring consistency between content visibility and link accessibility is vital for maintaining user trust and preventing unnecessary access roadblocks in our HPC user guides.

Connection Issues: Timeouts and SSL Problems

Beyond direct errors, our link checker also identified several connection issues that, while not outright broken links, can severely degrade the user experience. These manifest as timeouts or SSL certificate problems, preventing users from reaching the intended destination even if the link itself is syntactically correct. A timeout, like the ones seen for https://idsapp.vub.ac.be/pam/ in mkdocs/docs/HPC/account.md or https://shieldon.ugent.be/xdmod in mkdocs/docs/HPC/xdmod.md, occurs when a server takes too long to respond. This can be caused by server overload, slow network connections, or the server simply being temporarily down. For users, a timeout means endless loading screens and eventually, no content, leading to frustration and a perception of unreliability for our HPC services documentation. Equally concerning are SSL certificate errors, such as the SSL certificate hostname mismatch for https://elearning.bits.vib.be/courses/alphafold found in mkdocs/docs/HPC/gpu.md or the SSL certificate verification failed for https://www.straightrunning.com/XmingNotes/ in mkdocs/docs/HPC/running_interactive_jobs.md. SSL (Secure Sockets Layer) certificates are crucial for secure communication over the internet. When there's a mismatch or a verification failure, browsers will typically block access to the site, displaying alarming security warnings to the user. This not only prevents access to the content (like AlphaFold courses or Xming notes) but also erodes trust in the legitimacy and security of the linked resources within our documentation. Resolving SSL issues is paramount for VSC documentation security and user confidence. For external sites, we should investigate if the linked resource has a new, valid HTTPS URL or if an alternative, secure source for the information exists. If the issue lies with our own linked domains, it requires immediate attention from server administrators to correct certificate configurations or renew expired certificates. For timeouts, we can verify the status of the external services and consider adding disclaimers in our documentation if a service is known to be intermittently unavailable. We might also look for alternative, more stable resources to link to. Addressing these connection and security challenges ensures that users can not only find the information but also access it securely and efficiently, reinforcing the reliability of VSC resources and documentation.

Navigating Redirects: The Good, the Bad, and the Bumpy Roads in VSC Documentation

Redirects are a common and often necessary part of website management, guiding users and search engines from an old URL to a new one. Our report found 80 redirected links, indicated by a [200] Redirect: Followed X redirects resolving to the final status of: OK. While these ultimately lead to successful pages, it's crucial to understand their implications for our hpcugent and vsc_user_docs. A 301 redirect (Moved Permanently) is generally good for SEO when content has truly moved, as it passes most of the link equity to the new page. However, chains of multiple redirects can introduce delays, slowing down page load times and potentially frustrating users. For instance, the link https://account.vscentrum.be/ often involves 4 redirects before reaching the final page, as seen in mkdocs/docs/HPC/account.md, FAQ.md, quick_reference_guide.md, running_jobs_with_input_output_data.md, and troubleshooting.md. While the final status is
