I'm curious about the sub-domain https://marhamilresearch4.blob.core.windows.net. Are these auto-generated? I'm guessing these style of subdomains are not named by a human.

Looks like Azure Blob Storage and 'marhamilresearch4' is the name of the storage account (think website hosted in a public S3 bucket).

Azure requires these names are globally unique and only allows alphanumerics.

this is likely Mark Hamilton's static site deployed from his own blob storage account https://github.com/mhamilton723
