Can't access some websites

Last week I moved my website to a new server ( 90thBristolScouts.org.uk ) and now I can't access it or the webhost ( 34sp.com ) from VirginMedia. I get ERR_CONNECTION_TIMED_OUT. I can access them when using mobile data or a VPN.

I've waited a few days for the DNS to propagate and sort its self out but I still can't access the sites.

Here is the tracert to 34sp.com:

Any ideas what could cause it or how to fix it?
