That looks like it's good for accessing an html page.
So far the chinese are accessing the top level index, where 
files are offered for download at a click.

Ideally, if they can't access the top level, a direct address 
access to the files might be prevented?

The website's down after a fifth excursion pushed volumes above 
85g on a 70G temporary extension. What's the bet it was 17G 
accumulated in 262 'visits'. 

Can't ID that final hosts IP address while I'm locked out.

Luckily (~) for users, you can still access most of the usefull 
files, updated in January 2024, through the Wayback Machine.

https://web.archive.org/web/20240000000000*/http://www.ve3ute.ca/

Probably the best place for it, in some people's opinion, anyways.

YOU can make stuff available to others, in the future, by 'suggesting'
relevent site addresses to the Internet Archive, if they're not 
already being covered. 

Once a 'captcha' or other security device is added, you can kiss 
Wayback updates goodbye, as most bots will get the message.
I don't mind bots - thay can do good work.

Pity you can't just put stuff up in the public domain without 
this kind of bullshit.
