  • Free to use
    No account needed; Pro adds saved projects, PDF and CSV export
  • Domain still registered
    The domain alanaknows.com is still owned and registered, meaning the owner has the option to reactivate or rebuild the site in the future rather than losing the domain entirely.
  • Placeholder prevents dead link errors
    Instead of showing a generic browser error (like a DNS failure), the hosting provider displays a suspended page notice, which can be less confusing to visitors than a broken connection.
  • Potential for future content
    Since the domain is intact, if the account issue is resolved, the original website content could potentially be restored without needing to re-register the domain.
  • Clear indication of status
    The suspended page URL (cgi-sys/suspendedpage.cgi) clearly signals that this is a hosting-related suspension rather than the site being permanently deleted, which can help users or search engines understand the temporary nature of the outage.
  • No malicious content risk
    Because the site is suspended and not actively serving custom content, there is no current risk of the site hosting malware, spam, or other harmful material that active but neglected sites might accumulate.

Possible disadvantages

  • Website is completely inaccessible
    The main URL redirects to a suspended page, meaning visitors cannot access any actual content, information, or services that the site was intended to provide.
  • Unprofessional appearance
    A suspended page gives a poor impression to visitors, potential clients, or collaborators, suggesting neglect, financial issues, or abandonment of the site or associated business/brand.
  • Loss of SEO and traffic value
    Prolonged suspension can hurt search engine rankings and any previously built organic traffic, as search engines may de-index the site or lower its authority due to inaccessibility.
  • Unknown cause of suspension
    The suspension could be due to unpaid hosting bills, terms of service violations, or technical issues, and without more context, users or stakeholders cannot know the severity or how soon it might be resolved.
  • No information available
    Since the site is suspended, there is no way to evaluate the actual content, design, functionality, or purpose of the original website, making it impossible to assess its value or quality.

Questions & Answers

As answered by people managing LoadCairn and https://alanaknows.com/.

What makes your product unique?

LoadCairn's answer

Every calculator shows its formula, inputs and assumptions, with references to ASHRAE and NIST. Engineers can check the math instead of trusting a vendor tool that hides it.

Why should a person choose your product over its competitors?

LoadCairn's answer

Vendor calculators from APC, Eaton and Vertiv are tied to their own products and don't show their work. LoadCairn is vendor-neutral, free with no account, and covers power, cooling and facility metrics in one place. It also works offline in data halls with no signal.

How would you describe the primary audience of your product?

LoadCairn's answer

Critical facility engineers, data center technicians, facility managers, MEP consultants, data center project teams and students.

What's the story behind your product?

LoadCairn's answer

I've worked in data centers for 20 years. Most sizing still happens in old spreadsheets or vendor tools that won't show the math. I built LoadCairn so engineers have quick, transparent estimates they can defend in a design review.

Which are the primary technologies used for building your product?

LoadCairn's answer

A web app built on the Polsia platform. It installs on phone or laptop as a progressive web app (PWA) and works offline.

Who are some of the biggest customers of your product?

LoadCairn's answer

Not available at this thime.
