The W. Ross Ashby Digital Archive


As of 2018-03-08 my web hosting company is not serving the Alphabetical Index, Summary, and Timeline pages. Instead they appear to be substituting fraudulent,, and monetizing advertizing spyware in a hidden frame instead of these three 1MB pages! DON'T FOLLOW ANY LINKS TO THOSE PAGES WITHOUT A REPUTABLE SCRIPT BLOCKING BROWSER PLUG-IN! Currently, there's zero WRA Digital Archive content on those pages, just evil JavaScripting.

I recommend using the clean mirror site

There is an open support ticket for this issue with "". I will only remove this message when the problem has been fixed. - Mick

This is not an innocent mistake, they even went to the bother of faking the page title! This is the kind of shit that their server will send you instead of my 1MB pages:

Initially, it's reasonable to assume that the server copy of these pages have been hacked, and conclude that I only need to overwrite bad HTML files with clean ones to fix the problem, I tried it (see the Last modified date - European format) but that is not the case. The server copies of these pages are all approx 1MB and contain no monetizing JavaScript. Here's how it looks in my FTP client:

In a 2018-03-08 support chat, HostExcellence support guy Chris B. identified it as a ModSecurity issue and created ticket ID# 3652879 "mod security" - i.e. they are deliberately doing deep content manipulation of their client's web site HTML. That's not security. Presumably their monetization algorithm only targeted the site's most popular pages, but being 1MB somehow broke the page modification script, which broke the pages, and becomes a bit obvious when the HTML body tags are empty and the site users just see a blank white page!

2018-03-12 Update: I've created a clean mirrored version of the site on the domain.

Visit the clean mirror site

Still no action taken by for my 3 day old security ticket!

2018-03-19 Update: This site is still broken by my hosting company. Still no action taken by for my 10 day old security ticket! :-(

2018-03-20 Update: HostExcellence support are claiming that my 1MB pages are causing problems with their "security protocols" and that I have to make those pages (that have worked fine for over 12 years) smaller.

This is their response:

As you may know we recently implemented security procedures that caused these issues. We were able to whitelist some of the behaviors of the website that caused the broken images. That has been fixed.

For the other issue with certain pages loading white pages, this is due to the file size. While you are within the limits of your allowed disk usage, these security protocols look at certain file types and stop them if they are too large. For those pages that do not load, you will need to condense the size down by removing unnecessary code, or split it into multiple pages in order to bring down the file size.

I hope that this information helps.

My 2018-03-21 reply:

Those 1MB pages have worked for over 12 years and I cannot split them or make them smaller - they are generated.

Your messing with my site is only a security issue because YOU are inserting known malware: See

Your company is attempting to insert monetizing JavaScript that displays adverts in hidden frames, but my 1MB pages seem to break the code to use my visitors' browsers to perform click-fraud.

The only acceptable solutions are:
1) You modify your system to STOP inserting malware JavaScript into my pages.
2) You refund what I paid for you to host my site.

And the Oscar for the most unbelievable hosting monetization cluster-fuck-up goes to:
HostExcellence and Site5!
— which recently acquired HostExcellence. They obviously know the true meaning of the expressions "innovative-business-models" and "revenue-optimization". They, more than anyone else have truely redefined the meaning of the word "Excellence" when applied to web hosting!
Well done guys! And as it's International Women's Day, don't forget to thank your mothers, sisters, daughters, wives, girlfriends, employees, escorts, waitresses, table-dancers, ex-wives, ex-girlfriends, ex-employees, ex-escorts, ex-waitresses, and ex-table-dancers - who all know what a bunch of jerks you really are!

The W. Ross Ashby Digital Archive

William Ross Ashby (1903-1972) was a British pioneer in the fields of cybernetics and systems theory. He is best known for proposing the law of requisite variety, the principle of self-organization, intelligence amplification, the good regulator theorem, building the automatically stabilizing Homeostat, and his books Design for a Brain (1952) and An Introduction to Cybernetics (1956).

In 2003, Ross's family gave his journals, papers, and correspondence to the British Library, London. Then, in March 2004, on the last day of the W. Ross Ashby Centenary Conference, they announced the intention to make his journal available on the Internet. Four years later, this website fulfilled that promise, making this previously unpublished work available on-line.

The journal consists of 7,189 numbered pages in 25 volumes, and over 1,600 index cards. To make it easy to browse purposefully through so many images, extensive cross-linking has been added that is based on the keywords in Ross's original keyword index. To jump directly to a particular journal page, enter the page number here: then press Enter.

The biography describes Ross's life in more detail than has previously been available in the public domain, and includes many photographs from the family's private albums. Various other information and resources can be accessed via the navigation frame on the left.

In July 2017, at the International Society for the Systems Sciences conference in Vienna, Mick Ashby presented the ethical regulator theorem, which builds upon the good regulator theorem and the law of requisite variety. For more information, see The Ethical Regulator Theorem.
