On 29 December 2023, computer systems at Grenfell Campus, Memorial University were subject to a cybersecurity incident (which was subject of significant media coverage, e.g. here, here and here). This included the server which had hosted DistanceRegular.org since its launch in 2017, which was taken offline (possibly permanently). Consequently, the site was unavailable for a period of three months, until a new home could be found.
I am pleased to report that the site is now being hosted at the Department of Mathematics and Statistics at Memorial University's St. John's campus. Unfortunately this server does not support external domain names, so the URL "www.distanceregular.org" is now limited to reaching the home page. Pages on the site, including all data files, are reached via the URL "www.math.mun.ca/distanceregular"; so, for example, what was previously available at www.distanceregular.org/graphs/petersen.html can now only be found at
www.math.mun.ca/distanceregular/graphs/petersen.html.
The site was relaunched on 27 March 2024; at the same time an number of updates have occurred, as detailed here.
If you have any questions or comments, please contact me by email at robert.bailey@mun.ca.
Thank you for your patience!
