Boards of Canada has had an online presence for most of their career. These websites provide an interesting glimpse into the non-musical artist output of both the band and the Hexagon Sun collective.
EHX itself was started sometime in late 1996. It is not known when Boards of Canada's page was added, although it was mentioned in March 1997 usenet post advertising EHX. The earliest known archived copy is from December 6, 1998. The original location was at:
On September 20, 1999, the Boards of Canada site was relaunched as its own section at EHX. The new site was now located at:
The relaunched site was greatly expanded from the original EHX page, with multiple pages including an illustrated discography and audio clips.
The band finally left EHX in March 2000 when the page moved to the boardsofcanada.com domain name.
According to whois records, the domain name boardsofcanada.com was first registered on September 10, 1999. The earliest known archived copy, dated August 2000, was largely identical to the previous EHX sub-site. The front page changed from time to time but the main structure of the website remained the same.
By July 2001, the web page suddenly "went dark"; the previous multi-page site was replaced with a single front page with an image of the band, contact information and background music. 
The site was designed by designer James Tindall. A copy of the site is hosted at his page, Atomless, along with his comments about the site. The site was awarded a Prix Ars Electronica award for Net Excellence in 2003. 
The domain name hexagonsun.com was registered on September 9, 1999.
