Added to my hosts file (eventually! Win10 hates users being in charge of their own PC) but still doesn't work

Thanks for the update, I've just tested this on my home connection and I'm unable to load the site and I've got a static IP, the IP of the site 52.168.148.33 works fine though. @Kelly let me know if you need me to do any testing too.

The site loads for me at home where I have a static IP in the range 212.159.x.x. However nslookup results in
C:\nslookup wiki.ispace.org 212.159.6.10
Server: cdns02.plus.net
Address: 212.159.6.10
Non-authoritative answer:
Name: ispace.org
Address: 72.52.178.23
Aliases: wiki.ispace.org
which is a makedly different IP from the 52.168.148.33 mentioned in message #13 https://community.plus.net/t5/Everything-else/Website-blocked/m-p/1704363#M23187

So does that imply a DNS issue?

Hey @chrisboote,
To be honest I'm not sure what the next steps with this would be, it seems @Kelly was working on something behind the scenes or may have been investigating something. Might be worth awaiting his response.
Thanks.

I can't visit the page either, it's not blocked though.
Looks like it might be something todo with their DNS server, their aname and nameserver records seem to be fudged.

Seems like I managed to delete my reply when I deleted what I thought was a double post
I asked one of our engineers to have a look and they think there is something wrong with their DNS records:
Looks to be a DNSSEC configuration problem with the authoritive DNS server for this domain. This means that our servers aren’t able to validate the chain of security from the authoritive servers upwards. At a guess this is intermittent due to older cached records which may well be the problem as some may be correct, and some not.
Testing it from one of our cachedns servers fails locally and against the nameservers Jon mentions, giving a SERVFAIL response:
root@cachedns07:~# dig wiki.lspace.org +cmd
; <<>> DiG 9.9.5-9+deb8u18-Debian <<>> wiki.lspace.org +cmd
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 74
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
root@cachedns07:~# dig wiki.lspace.org +nocmd @dns1.registrar-servers.com

;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 20411
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
Running the check with an additional flag to disable DNSSEC checking resolves locally, but still fails against the others:
root@cachedns07:~# dig wiki.lspace.org +nocmd +cd @dns1.registrar-servers.com
; <<>> DiG 9.9.5-9+deb8u18-Debian <<>> wiki.lspace.org +nocmd +cd @dns1.registrar-servers.com

But I can open it when I'm accessing with 4G, or from work
Only fails when opening it from PlusNet broadband

Just checked again and the site appears to be working normally now for me.

Hi,
Have you tried reaching out to the site owners to see if they've something wrong on our side?

@chrisboote Another work around would be to enable safeguard and then turn off the filters (unless you want them on). That means you'll be assigned a different set of DNS servers which might not see the issue? (If this works, I'd be interested to see!)
