How does the Plusnet Caching Nework actually work?

Okay, in light of Baldrick1's topic here I made the following comments

 

https://www.plus.net/features/network/index.shtml

Unlike many ISPs, PlusNet own and manage their broadband platform.

 

https://www.plus.net/features/network/technical_info.shtml

We closely monitor our network capacity, investment is made to to provide both extra bandwidth and network resilience as customer numbers and demand requires.

The network is linked to the following transit providers: Tiscali and British Telecom.

https://www.plus.net/help/broadband/about-broadband-allowances/#internet-caching

The Plusnet Internet Cache has got me thinking (from last link above)

is a way to bring Internet content that users regularly request closer to them within our network, so that you can more easily and quickly access the content you need.

...

We do this by hosting the content on the Plusnet network, rather than you having to request it from servers further away over the Internet.

 

Assuming it isn't a commercial secret, what's the full content list that Plusnet hosts within it's network?

Do the tests we are asked to perform (ie tracerts) now become redundant?

How do we prove where the issue actually lies?

If the content is within the Plusnet network, does Plusnet monitor that usage more closely?

Does Plusnet use (if the do) this 'big brother' data to target us?

Do they keep it, or pass it on to third parties, or sell it on?

Do I need a tin foil hat?

Have I got this wrong?

 

 

ps. KISS please

(Keep It Simple Stupid)

TIA

Re: How does the Plusnet Caching Nework actually work?

Furthermore, am I missing something here?

(I've already mentioned this on various topics, but gonna try here as I think it's more related to the above)

 

When I carry out a tracert to these forums I often see multiple different destination IP's, even quick repeated tracerts differ.

However, upon verifying, these do not match what my browser is showing (and also recently reinstalled FlagFox to confirm)

 

My browser at the time of typing this gives https://iplookup.flagfox.net/?ip=52.222.231.253&host=community.plus.net

And based on the last traceroute, checked at the same time (as close to anyway):

tracert community.plus.net

Tracing route to d14xs8zr41zt1m.cloudfront.net [99.84.8.47]
over a maximum of 30 hops:

...
18 10 ms 10 ms 10 ms server-99-84-8-47.lhr62.r.cloudfront.net [99.84.8.47]

 

It gives me the 99.84.8.47 IP as the destination, yet putting that IP straight into my URL window on any browser gives:

403 ERROR
The request could not be satisfied.
Bad request.

Generated by cloudfront (CloudFront)
Request ID: <redacted>==

 

So, are these forums hosted on Plusnets internal caching network or not?

(trying to suss out if tracerts are now valid on the Plusnet network)

And by putting different website IP addresses straight into the URL they also fail to load, with various error messages. I'm fairly sure you could do that before...? But now I can'tHuh

 

edit. By typing in a random IP, which I'd of thought would take you to that site gives:

Forbidden
You don't have permission to access / on this server.

(but I'm only trying to get to the site, using it's IP, not access it's server)

Am I getting this wrong?
